Audio stream client-server for chat rooms

We want to have a solution in either activex or java or flash. using a free server like shoutcast. In a chat environment we want to add audio feature. Here is the scenario: When person1 is in his room he can broadcast audio to all the people that are in his room. we figure that there would be a flash (or else) component in to broadcast is person1 room and another flash (or else) component in the invitee room to listen to person1 audi. a parameter of the listener component should identify which audio stream is to be listened. needs to be going through a multicast server to support many connections on the same stream. there is already existing controls on the net, you can just find them and provide to us the finished solution. Basically we want something like [login to view URL] but embedded broadcasting and receiving audio through controls in a webpage. Our website is [login to view URL] we already have the chat and video, we jjust want to add the audio, ## 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 broadcast: window98 and up server : window 2000 server or window 2000 pro
