Create Online Video-Chat room that can be watched by any number of viewers

[ggibin]

Hi all,

I´m starting off from a raw concept and I wonder if anyone can give me a tip or point out the right technology to use to achieve what I want with low or no cost. Thanks a lot in advance.

THE CONCEPT
I want to build an online 2 people video chatroom where both participants have their webcams stream to the same window (split just like interviews on the news)

A. I want any number of people to be able to connect to my website, and just watch, those first two people video-chat in real time
B. I want to be able to record the video chat (two webcams split into the same video) into my server or somewhere else in real time

Please help; any tips are most welcome!

Thanks a lot!
