If you have any specific questions, let me know. I've been running an internet radio station on and off for 5 years or so (the past year I've finally been able to keep it up 24/7).

I use a combination of custom software and Shout.pm, a Perl interface to libshout, a library for streaming to a Shoutcastish server.

My server's front page is located here.

And I would like to point out because it's so damn funny is that one (1) (uno) (single) day after writing this (especially the "up 24/7" bit) I had my connection pulled due to bandwidth limits.
