My part here is just to throw a series of questions. 
- How can we build a audio/video chat and a white board in flash?
- Do we need a streaming server for this? ( ie., Do we need to buy a separate space in
a web server for that purpose? If so list them …) - What is streaming server?
- What is rtmp?
- What is flash media server?
- What is flash communication server?
- What is Red 5 ?
- How can we integrate those technologies with flash ?
- Is there any examples and resources available in web?
- If so what are they?
