I am interested in streaming audio files over the internet. I have legal bootlegs that I'm getting permission to use (by the artist), and would like to stream it like those internet radio stations.

I was wondering how the whole thing worked. The only one I've really used is the one at www.rilokiley.net which appears to be run with Shoutcast. I looked into that, and it appeals to me, except that I don't like having to stream it from my desktop computer. Is there a solution that will work from my web server? How much bandwidth does that take up? How much for each additional person listening?

Thanks for any help.
