Awesome. Still having trouble getting it to work but that doesn't
matter, it looks cool anyway. Probably because I don't have multicast
support.

I have a lightweight config file module from ogg123 if you want a
quick config interface for the server; it could also be used for SDP
file parsing from the looks of things, but with all the hardcoded
things in the streamer it would be worth the minimal effort to add it
at least for the URLs, IPs, and interfaces.

Yes, plenty of those. But you're a better programmer than I so I won't
try to fix them. :)

Curl's pretty easy, as you've probably noticed already. Loading common
codebooks (and identifying them by md5sum) would be a nice way to save
a few kilobytes.

Good luck with further work! I hope to use some of what you come up
with for ogg123 streaming support, and what exists looks promising.
