Video Conferencing Application on Windows - repost

We need a video conferencing application that will work on Windows 7 using H.264 codec. It needs to provide point to point high definition video communication on IP network. Simply the application will connect to the other application using IP address and a specific port, then encode webcam's video stream using H.264 codec and send this datastream to the destination. On the other side, application will listen on a specific port. When there is a incoming request, it will answer the request and receive encoded video and display it. Also it will encode and send its own video stream. The encoding and decoding should be done using H.264. Here are the other requirements: * 1080p/720p video resolution, * 30 frames per second, * maximum bandwith usage should be 6mbps dowstream and 6 mpbs upstream, * .NET application is preferred, * Lag on local area network should be less than 10ms. P.S. If you think that a specific technical requirement can not be met or it may require specific hardware, please mention in your bid.
