Video/Audio Broadcasting

We need an application to broadcast Audio & Video from a computer to a large list of observers (from 10 to 1000)Yahoo has a service to do this but we need to broadcast our conferences across the country in december and I can´t make Yahoo to answer my request. Tips 1. The computer which has the cammera and microphone isn´t the Web Server. 2. I have a Broadband connection of 64K to Internet 3. I think we need 3 applications to run together: a) The applications that captures the Audio & Video from the cammera and sends it to the Web or Application Server (where we can buy a 1 Mb. broadband) b) The application, hosted at USA ([login to view URL]) from where it broadcast the signal. c) The Client Application that receives the A&V signal and shows it on Screen and on Speakers. The application must include a Chat facility and the ability of sending and receiving files and HTML content. If you can see the Yahoo solution, it´s just what we need. Please guide me if there is another alternative more efficient to develop that application. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform Internet / Windows ## Deadline information Please send your suggestions and a diagram of work.
