The present invention disclosed and claimed herein relates to real-time information exchange between a plurality of users in a multimedia conferencing environment The system can provide meeting functionality for users in disparate locations (eg ,a user in a conference room and a user in a remote office), or users located in a single conference room Vanous technologies can be employed to facilitate real-time information exchange, comprising, for example, microphone arrays that provide high-fidelity audio, and directional information The system can also comprise a room camera with digital automatic pan/tilt/zoom framing of persons speaking, and/or automatic warping to equalize people's face sizes, no matter where they sit m the conference room Additionally, live transmission and snapshot capture of physical whiteboard contents can be facilitated via, for example, a web-camera to preserve and/or disseminate meeting notes displayed thereon "Capture-and-send" functionality can be provided to permit quick capture and transmission of paper annotations, and furthermore can be provided with tablet PC integration for transmission of ink annotations This aspect permits transmission of captured documents without requiring printing and faxmg, etc A further aspect of the invention comprises a drag-and-drop interface that enables a user to transfer files between a Data Server database and the user's own hard drive Additionally, a Presentation Chute can be provided for broadcasting a document, for example, a PowerPoint presentation, etc, to other users attending the conference and receiving Data Client can take appropriate actions with regard to the document based on the document type and other metadata associated with the document Still furthermore, the invention provides for recording and automatic indexing of meetings, so that the audio content is searchable via vanous interfaces, such as Outlook and/or SharePoint According to an aspect of the invention, a system is provided via which one or more user interfaces (UIs) is presented to a user to facilitate real-time conferencing between at least two participants, which can be physically located m the same conference room and/or in located remotely from each other The system provides both real-time audio/video communication and real-time data collaboration A video component can be provided that facilitates both video imagery and still images. Additionally, the video component can automatically warp an image and/or video for presentation to a user In this manner the system can present a conference room environment to a user in real-time while permitting users to capture and transmit in real-time video and/or still images of, for example, documents, a chalk board, a white board, etc, or any other pertinent piece of information that a first user might desire to share with a second user The video component can comprise a video camera that captures video of, for example, a conference room and people therein, and a separate web camera that can capture video and/or still images of, for example, a white board containing meeting notes, a paper document, etc The system also comprises an audio component that provides real-time audio functionality in a conferencing environment Additionally, a Virtual Director is provided that can coordinate audio and video components to provide an enriched conferencing experience to a user According to a related aspect of the invention, a Data Client UI can provide a Presentation Chute to each user to facilitate real-tune document sharing and/or presentation viewing For example, a Presentation Chute icon can be presented via the UI and can permit a user to drag a document (e g, a photo, a Word file, a PowerPoint presentation, etc ) to the icon, drop the document on the icon, and the system can then upload the document to the Data Server for dissemination to all other data clients attending the virtual conference For instance, if a presentation document is dropped in the Presentation Chute, such as a PowerPomt presentation, the sender can select to have the presentation automatically begin at another user's UI, or can select to have the Data Server first determine the capabilities of the other user's computer in order to facilitate providing a best mode for the presentation. For example, if the receiving user is attending the virtual conference via a handheld computer, such as a PDA or a cell phone, then the UI presented to that user will have limited capabilities as compared with a laptop, etc In such a case, the Data Server can wrap a presentation m, for example, PowerPoint Viewer, or any other suitable package to permit the presentation to be viewed by the receiving user despite the relatively limited capabilities of the receiving user's UI Thus, the system can support two modes of data sharing For example, data can be sent from one Data Client to another in native format, or, alternatively, data can be formatted appropnately to enable viewing (e g, not sent as a raw file), to permit a recipient to view the data without editing capabilities According to another aspect of the present invention, a Room Server PC is provided that comprises a Room Server that centrally controls components associated with virtual conference The Room Server PC further comprises a separate Data Server and an AV Server that can be coordinated by the Room Server All Data Clients in attendance at a virtual meeting are connected to and coordinated by the Data Server Additionally, an audio-video (AV) client can run on the Room Server PC, and is separate and distinct from a Data Client associated with a virtual conferencing system The AV Client comprises software that facilitates providing video and/or still images of a conference environment and permits a user to selectively zoom, pan, and/or tilt a digital automatic pan/tilt/zoom (DPTZ) camera located in the conference environment The AV Client also permits manipulation of audio data, such as noise reduction, gam control to permit amplification of a speaker's voice located further from, for example, a microphone array in the conference environment, as opposed to a speaker located nearer the microphone array, etc. The Data Client can be run on, for example, a laptop, PDA, cell phone, or any other suitable UI for attending a virtual conference, and can be located in the conference room or at a remote location, such as an office in another building, city, country, etc The Data Client software provides functionality to permit users to share files via a drag-and-drop interface, to broadcast documents via a Presentation Chute, etc Thus, while both the Data Client and the AV Client are software modules composing UIs, they can exist as separate entities wherein the AV Client handles capture, transmission, and/or rendering of AV content (eg, AV communication), and the Data Client handles data collaboration (e g, file transfer, presentation broadcast, etc) By separating the A V Client front the Data Client, a user can be permitted to conduct data collaboration without AV communication, to conduct only AV communication without data collaboration (e g, via employing a cell phone as an audio channel, etc ), and/or concurrently to conduct both data collaboration and AV communication According to yet another aspect of the invention, a web camera is provided that facilitates high-resolution digital capture of, for example, documents, white board contents, etc., that a user in a conference room wishes to share with at least one other user in the conference environment This aspect of the invention permits a hard copy of a document to be transformed into an electronic copy of the document for rapid dissemination and/or for review by at least one user during a virtual conference and/or at a later, more convenient time This can be particularly useful with respect to white board contents, such as algorithms, sketches, etc, which can be permanently preserved in electronic form for review, thereby mitigating any risk of white board contents being accidentally or inadvertently erased from the board Images captured by the web camera can be automatically stored at an AV Server and presented, pnnt-ready, to participants in the virtual conference. Furthermore, the web camera can be mobile and can be moved about the conference environment to facilitate capturing a document resting horizontally on a table, a statement on a vertical white board, etc Additionally, the web camera can be plugged into any computer in the conference environment {eg, conference room, remote office, etc ) in order to be utilized According to still another aspect of the invention, an automatic discovery functionality can be provided by which a user who is approved to attend a virtual meeting can be notified that the meeting is in session, about to start, etc. For example, a user can receive an email notification from a Room Server that the virtual conference is about to start, etc Additionally, when a user enters a predetermined penmeter associated with the Room Server, the user can be invited to join the virtual conference User invitations can be selectively predicated on a guest list that can verify user identification via email address, internet protocol (IP) address associated with the user's laptop, PDA, cell phone, etc, or by any other suitable means of identifying a particular user's computing device Furthermore, virtual conference access can be password-protected to ensure that the user at the computing device is who the user purports to be To the accomplishment of the foregoing and related ends, certain illustrative aspects of the invention are described herein in connection with the following description and the annexed drawings These aspects are indicative, however, of but a few of the various ways in which the principles of the invention may be employed and the present invention is intended to include all such aspects and their equivalents Other advantages and novel features of the invention may become apparent from the following detailed description of the invention when considered m conjunction with the drawings BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is an illustration of a system 100 that facilitates real-time information exchange and data collaboration in a multimedia conferencing environment compnsing audio/video (AV) clients that permit AV communication and separate Data Clients that provide data collaboration functionality in accordance with an aspect of the present invention Figure 2 is an illustration of a system 200 that comprises a processor and memory to facilitate real-time information exchange and data collaboration in a multimedia conferencing environment in accordance with an aspect of the present invention Figure 3 is an illustration of a system 300 that comprises an artificial intelligence component that makes inferences to facilitate real-time information exchange and data collaboration in a multimedia conferencing environment in accordance with an aspect of the present invention Figure 4 is an illustration of a system 400 that facilitates real-time information exchange via employing a digital automatic pan/tilt/zoom camera and/or a web camera in a multimedia conferencing environment in accordance with an aspect of the present invention.

The Virtual Director 410 can direct the DPTZ camera 422 to frame a person speaking at a given moment in the conference room and such imagery can be received by the an AV Server 428 residing in the Room Server PC 402 and disseminated in real time via the UI associated with the AV Client 412 For example, transmitting a video of a conference room at high-resolution requires a significant amount of information to be sent The Virtual Director can mitigate large transmissions by presenting a speaking person in high resolution while presenting the rest of an image of the conference room in low resolution By transmitting the majority of an image in low resolution, the size of a transmission can be significantly reduced Additionally, the DPTZ camera 422 can provide an automatic warp functionality whereby the size of each attendee present in the conference room can be equalized despite the relative distance of each attendee from the DPTZ camera 422 This particular aspect of the invention will be discussed in further detail infra The video component 404 can further comprise a document capture component 424, such as a web camera, that permits hard copies of documents to be transformed into electronic copies that can be presented in real time to each user For example, the document capture component can take a still image of a paper document, a white board containing meeting notes, etc, and preserve such documents electronically for subsequent review, etc Furthermore, once captured, documents can be instantly disseminated to users in a ready-to-prmt format Figure 5 illustrates a system 500 that facilitates real-time multimedia information exchange in a conferencing environment in accordance with an aspect of the present invention A Room Server PC 502 is operably coupled to a video component 504 that monitors a conference room environment to capture video data associate with, for example a conference, and an audio component 506 that monitors a conference room to glean audio information related thereto The Room Server PC 502 is further operatively associated with a Data Client 508 that provides data collaboration functionality and can present information received from a Room Server (not shown) on the Room Server PC 502 to a user via a user interface 514 The Room Server PC 502 comprises a Virtual Director 510 that facilitates automated control of AV information dissemination and/or collection, and an AV Client 512 that provides software applications, programs, processes, threads, etc, to facilitate receipt and/or dissemination of information in audio and/or video format(s). It is to be noted that the AV Client 512 is separate and distinct from the Data Client 508, which facilitates mitigating a need for a separate AV Client at each local user's personal computing device The Virtual Director 510 is associated with a processor 516 that facilitates control of various components of the system 500 and/or analyzes information received there from The Virtual Director 510 is further associated with a memory 518 that can store information received from system components and/or analyzed by the processor 518 Additionally, the Virtual Director 510 comprises an AI component 520 that can make inferences regarding, for example, information dissemination to at least one user etc The video component 504 comprises a DPTZ camera that can monitor, for example, a conference room environment Individual remote users can selectively zoom, pan, tilt, etc, to different regions of a real-time image presented to the remote user via respective AV Clients 512 launched on remote users' computing devices This aspect of the invention can be especially useful to a user attending a conference from a location disparate to the physical location of the Room Server PC 502 m a conference room The video component 504 further comprises a document capture component 524 that can capture images of documents, such as, for example, a hard copy of a memo, meeting notes on a white board, or any other document that a user desires to preserve in electronic form and/or share with remote users Such images can be immediately presented to all users, such that upon capturing an image, the image immediately appears to the user and is ready to print if the user desires The audio component 506 comprises a microphone array 526 and a speaker tracking component 528 Although the speaker tracking component 528 is illustrated as being comprised by the audio component 506, it is to be appreciated the speaker tracking component 528 can be comprised by the an AV Client 512 and/or the Virtual Director 510, and is not limited to the physical orientation in which it is illustrated in Figure 5 The microphone array 526 can provide high-fidelity, noise-free capture of audio information. Furthermore, the microphone array can provide directional information that can be analyzed, for example, to determine the location of a person who is speaking in a conference room via the speaker tracking component Additionally, vision-based tracking can be facilitated by, for example, the Virtual Director 510 based at least tn part on data received from the video component 504 {eg, a. wide-angle web camera, DZPT camera, etc ) Such can be particularly useful m scenanos comprising a large volume environment noise, such as applause, and room reflection, wherein the accuracy of a microphone array can be compromised Video captured by the wide-angle room camera can be employed by a vision-based tracking algorithm (e g, motion-based, appearance-based, particle filter based approaches, etc ) Furthermore, directional information from the microphone array and vision-based tracking results can be fused by, for example, a particle filter (not shown) (or other appropriate machine-learning techmque(s)) associated with the Virtual Director 510, to produce more accurate and robust tracking results than either of the microphone array directional information or vision-based tracking information alone The Room Server PC 502 further compnses an AV Server 530 that coordinates AV communication between the AV Client 512 in the Room Server PC 502 and, for example, a remote AV Client (not shown) launched by a remote user on a remote PC Additionally, the Room Server PC 502 compnses a Data Server 532 that coordinates data collaboration between two or more Data Clients 508, whether running on a remote PC or on a local PC present in the conference room. It is to be appreciated that a Data Client 508 can be run on the Room Server PC 502 in addition to the AV Client 512, but is not required to be run thereon Figure 6 is an illustration of a basic conferencing environment 600 in accordance with an aspect of the present invention. According to the figure, the conferencing environment 600 compnses a Room Server PC 602 and at least two Data Clients 604, which can reside on users' computing devices, such as laptops, tablet PCs, and the like Optionally, a Data Client 604 can reside on the Room Server PC 602. Each Data Client 604, illustrated as a laptop m Figure 6, provides data collaboration capability to a user According to an aspect of the invention, a user who enters the conference room with a Data Client 604, running on a laptop ,a tablet PC, etc, can be identified by the a Room Server residing on the Room Server PC 602 and invited to join the conference For example, the user can be identified via an IP address associated with the Data Client 604, an email address associated with the Data Client 604 and/or user, a unique universal resource locator (URL) ID generated by the Room Server for each meeting, etc Furthermore, the user can be prompted to enter a password to venfy that the user of the Data Client 604 is actually the person who the user purports to be (e g, a person who is invited to the conference, meeting, etc ) The Room Server PC 602 can compnse and govern a Data Server that facilitates data collaboration between Data Clients 604 For example, each Data Client 604 compnses drag-and-drop file transfer capabilities, such that a user can drag files between "local" and "server" regions presented to a user as part of a user interface (UI) associated with each Data Client 604, and the file immediately will be copied from the Data Client 604 to the Data Server in Room Server PC 602, and vice-versa Once a file is copied to the Data Server in the Room Server PC, all attendees at the meeting have complete access to the file The file can be document, such as a word processing document, a spreadsheet, or any other suitable file capable of being created, transferred, stored, etc A related aspect of the invention provides for drag-and-drop file broadcast capabilities via a "Presentation Chute" presented to a user as part of a user interface (UI) associated with each Data Client 604. According to this aspect, a presentation file, such as, for example, a PowerPoint presentation, can be dragged over and released upon the Presentation Chute Once placed in the chute, the presentation can be immediately presented via the Data Server in the Room Server PC 602 to other Data Clients 604 in attendance at the meeting, regardless of whether the other Data Clients 604 are remote or local. Additionally, the sender of the presentation can have increased control over the presentation as compared to the amount of control granted to recipients of the document For example, if a first user transmits a presentation to a second user, the first user can require that the presentation slides can only be advanced upon the first user's prompt (e g, a mouse-click, stylus tap, voice prompt, ) Alternatively, the first user can "unlock" presentation control and permit other users to advance the presentation at will According to this example, a plurality of recipient users can view the presentation at different rates, according to their individual needs. The Presentation Chute will be discussed in greater detail infra, with regard to Figure 7 Figure 7 illustrates an exemplary UI 700 that can be presented to a user via a Data Client The UI 700 comprises a "server files" region 702 that comprises server file icons 704 representing files stored on a Room Server m a conference room The UI 700 further comprises a "local files" region 706 that comprises local file icons 708 representative of files stored locally on a Data Client on which the UI 700 is presented to a user Thus, while the server file icons 704 in the server files region 702 will be the same for each Data Client attending a conference, the local file icons 708 in the local files region 706 can vary from one Data Client to the next, although it is possible that two or more Data Clients will have the same set of local files represented as local file icons 708 in the local file region 706 of the UI 700 A user can drag an icon 708 from the local file region 706 and release it in the server file region 702 to cause the local file to be uploaded to the server, permitting other users to receive and/or access the file in their respective server file regions 702 Additionally, a user can drag-and-drop a server file icon 704 on the local file region 706 to copy the server file to the user's local hard drive The UI 700 comprises a Presentation Chute 710 that facilitates presentation sharing between Data Clients For example a can drag a presentation file (e g, an electronic slide presentation, PowerPomt presentation, etc ) over the Presentation Chute 710 and release it thereon for upload to the Data Server Transmission to the Data Server can be accompanied by sound effects to notify the user that upload is m progress The Data Server can then initiate a file broadcast to other Data Clients attending a meeting Each Data Client can then individually launch an appropriate Data Viewer to show the presentation The user who initially places the presentation file in the Presentation Chute 710 can be considered the owner of the presentation, and can control scrolling operations {e g, previous, next, etc ) during the presentation Alternatively, the owner can permit desynchromzation among users at receiving Data Clients, such that receiving users can be permitted to skip ahead, revert to previous slides, and generally view the presentation at their own paces In this case, each UI can provide a "Sync" icon (not shown) that, when clicked on, will automatically synchronize the presentation on the receiving Data Client to the owner's view of the presentation Additionally, the owner's Data Client can have a master "Sync" icon (not shown) that will synchronize all Data Client views to the owner's view when activated Turning now to figure 8, a conference environment 800 is illustrated in accordance with an aspect of the present invention According to the figure, the conference environment 800 comprises a conference room 802 with a Room Server PC 804 The conference room 802 further comprises at least one Data Client 806, residing m for example a laptop, a tablet PC, a handheld computing device, or any other device suitable to present a user interface to a user m conjunction with aspects of the present invention set forth herein The conference room 802 further comprises a remote user Stand-in Device 808 that facilitates presenting a remote user in near-life size to users located m the conference room and vice versa The Stand-in Device 808 comprises a display 810 (e g, a monitor, a flat panel display, .), upon which are mounted a DPTZ camera 812, a microphone array 814, and speakers 816 It is to be appreciated that there can be one or a plurality of remote Stand-in Devices depending on the number of remote users attending a meeting Additionally, a single remote Stand-in Device can be employed to represent multiple remote users (e g,via a split-screen, picture-m-picture technology, etc ) The Stand-m Device 808 is operatively coupled to the Room Server PC 802 The DPTZ camera 812 captures images of the conference room and people therein and such information is received by a local AV Client in communication with an AV Server in the Room Server PC 804, for presentation to a remote user via an AV Client running on the remote user's PC. The DPTZ camera 812 can automatically warp images of the conference room so that attendees located therein are presented at roughly the same size, despite an individual's actual distance from the DPTZ camera 812, as is described in more detail with respect to Figure 9 Automatic warping facilitates allowing a remote user (or, eg, a Virtual Director, as described with reference to Figures 1-5), to zoom into any person, including those situated far from the DPTZ camera 812 The microphone array 814 captures sound from the conference room, such as a speaker's voice, and provides information associated therewith to the AV Client m the Room Server PC 804 for presentation to the remote user Additionally, the microphone array 814 can provide position information related to a speaker's position, for example, to a Virtual Director in the Room Server PC 804, which can employ the position information to direct the DPTZ camera 812 to zoom to the position of the speaker Such zooming can additionally be performed by a remote user according to a related aspect of the invention Additionally, vision-based tracking can be facilitated by the Virtual Director based on data received from the DPTZ camera 812 Video captured by the DPTZ camera 812 can be employed by a vision-based tracking algorithm (e g, motion-based, appearance-based, particle filter based approaches, etc ) to determine speaker location Furthermore, directional information from the microphone array and vision-based tracking information from the DPTZ camera 812 can be fused together by a particle filter (or other appropnate machine-learning techmque(s)) to produce more accurate and robust tracking results than either of the microphone array directional information or vision-based tracking information alone According to a further aspect of the invention, a speaker can be presented to the remote user in high resolution in addition to a low resolution video of the conference room, such that when a speaker begins to speak, position information received by the AV Client (e g, microphone array directional information and/or vision-based tracking information) in the Room Server PC 804 is used by the Virtual Director to determine the location of the speaker withm the conference room, and the DPTZ camera 812 is directed to present that location in high resolution in addition to a low resolution video of the conference room. By permitting the resolution of the image to be reduced, bandwidth constraints can be mitigated when present The microphone array 814 can be supported by a real-time communication audio stack, and can provide automatic echo cancellation, sound source localization, noise suppression (e.g of localized noise source(s)), and/or gam control to facilitate audibility with respect to distant speakers The speakers) 816 are provided in conjunction with the Stand-in Device 808 to present audio information to users in the conference room from the remote location In this manner, the remote user can speak to attendees in the conference room from the remote office 818a-818n Each remote user has a computer that can comprise its own AV Client to facilitate reception of AV-related information from the conference room Additionally, the remote user's computer can comprise a Data Client that facilitates data collaboration between the remote Data Client and the Data Server m the Room Server PC 804 and/or Data Client(s) 806 in the conference room. Each remote office 818a-818n can be equipped with a microphone (not shown) and a web camera (not shown) to capture AV information in the remote office for transmission via an AV Client running m the remote office to the AV Server m the Room Server PC 804 and presentation on the remote Stand-m Device 808. It is to be appreciated that the remote user can employ, for example, a cellular phone as a UI if necessary, and can view the conference room via the wide-angle digital video camera on the remote Stand-m Device if the cellular phone has video functionality However, the cellular phone can be utilized to provide audio functionality at a minimum, such that the remote user can hear and be heard in the conference room 802 The remote user in this scenano can be notified of the initiation of the meeting by, for example, a call to the cellular phone placed by the server 804, by another attendee at the meeting, etc Additionally, the remote user in this example will only launch an AV Client, as no Data Client is desired by the remote user Figure 9 is an exemplary illustration of an image presented on a user interface associated with an AV Client of a conference room before and after automatic warping by the AV Client, Virtual Director, etc As illustrated, the first image 902 depicts a conference room in which four attendees sit at various distances from a DPTZ camera The attendee at the end of the table is perceived at an exaggerated distance compared to other attendees to the conference. After warping, the image 904 of the conference room presents all attendees in a more equalized arrangement, such that the relative distances of the attendees from the DPTZ camera is still perceivable, but each individual attendee is presented as having a size relatively equal to every other attendee Thus, the image 904 more closely resembles the view that would be perceived by a person physically present in the room Automatic warping operates by identifying a different magnification power to be applied to each vertical scanhne in an unwarped image For example, in most cases the center of the image is expanded more while the sides may not be enlarged The magnification vanes smoothly across the image, thus minimizing distortion in any local area This results a wider but more uniform view of the conference room as opposed to a view with wide-angle distortion The automatic warping of conference room images facilitates an enriched conferencing expenence for the remote user(s) Figure 10 illustrates a conferencing environment 1000 similar to that descnbed in Figure 6, in accordance with an aspect of the present invention The conference environment 1000 compnses a conference room 1002 with a Room Server PC 1004 compnsmg a Room Server that facilitates centralized control over a Data Server and an AV Server, and at least one Data Client 1006 A Stand-in Device 1008 is illustrated that represents a remote user in a remote office 1014a-n as descnbed with respect to Figure 8, where the Stand-m Device comprises the features and functionalities descnbed therein It is to be appreciated, however, that the presently descnbed conference environment 1000 can comprise two or more Data Clients 1006 located m the conference room without a remote user The conference environment 1000 further composes a high-resolution web camera 1010 that facilitates capturing images of, for example, a paper document (not shown) and/or a white board 1012 As used herein, "document" is intended to comprise a document, sketch, etc, written on a white board The web camera 1010 can be directed at, for example, the white board 1012, and images captured thereby can be presented to all users via user interfaces associated with AV Clients running in each location, whether tn the conference room 1002 or m a remote office 1014a-n Such imagery can be presented m real time, which facilitates real-time updates to the white board such that erasures, additions, and/or any other changes to the white board can be perceived by remote user(s) as well as to users physically present in the conference room 1002 Additionally, the web camera 1010 can capture still images, such that if no further changes will be made to the white board content, a still image of the white board 1012 can be captured and presented by an AV Client running m the location of the white board to an AV Server in the Room Server PC 1004 for dissemination to AV Client(s) local to other users for storage and/or later review It is to be appreciated that the present invention is not limited m application to a single conference room 1002, but rather can facilitate real-time multimedia information exchange between any number of disparately located conference rooms and/or offices, regardless of geographical location and/or proximity to one another. The single primary conference room 1002 is presented herein for purposes of illustration only and is not intended to limited number of conference locations, rooms, offices, etc, in and/or between which the present invention can operate Additionally, a web camera can be provided in any remote office, secondary conference site, etc, to facilitate document and/or white board image capture at the remote location for presentation to other AV Clients Furthermore, a physical document can be digitally photographed by the web camera 1010 and immediately transmitted to AV Chent(s) via an AV Server for user review, printing, signature, etc Such a "capture-and-send" protocol can comprise image capture of a document and/or whiteboard, enhancement of the image, and immediate transmission For example, a remote user who receives a captured image of a document requiring the remote user's signature can print the document, sign it, and employ a second web camera (not shown) at the remote location to capture an image of the signed document and immediately transmit the image back to the original sender of the document The onginal sender can then pnnt the signed document, store it electronically, etc If a signing user is employing a tablet PC to run the AV Client, then the signing user can sign electronically utilizing a tablet stylus, without having to pnnt the document and/or employ a second web camera before retransmitting the signed document Example Scenario To illustrate the operation of the above-descnbed system(s), the following example is proffered.
