A client has contacted me about live streaming. He wants to broadcast a live meeting over the internet so that other people can watch it.

I've never looked in to something like this - I guess I need to find some software that will let me re-broadcast the stream - ie someone at the meeting would connect to my server and stream it up to the server, and my server would then broadcast it out to anyone who is connected.

So, what sort of software should I be looking at? Are there any guides around on the internet or anything that can help me out?
