streaming video server

[Kyle Waters]

So, I'm interested in setting up a streaming video server.  Someone 
would run a client on their laptop with a web cam and connect to the 
server, the server would then stream the video out to users of the 
website(a delay up to ten minutes is acceptable).  I've found some 
commercial software available to do this but would of course prefer free 
software, or at least server side solutions that run on linux. Does any 
one have any experience or suggestions, third party integrate solutions 
are acceptable.
