Why not use Quicktime Broadcaster? It's free, and it can do multicast. We use QT Broadcaster to multicast television on our Digital Academic Television Network <http://datn.wisc.edu/> (click on "About" to learn more). There is also a Quicktime Streaming Server if you want to serve up multiple unicast streams, but Broadcaster does multicast by itself.

Okay, I've set myself the task of setting up a PPC Mac Mini as an 'appliance', if you will, to sit in a radio station and provide a live multicast audio stream fed to it's line-in. The OS X port of VLC won't accept anything other than files or network streams as input, so no piping of audio into stdin or yoinking the audio straight out of CoreAudio (as you can do with DirectShow on Windows or /dev/dsp on *nix). I've gotten around this so far by installing EsounD (the Enlightened Sound Daemon) and esdrec to get the system audio and pipe it into lame which is, in turn, piping into the aforementioned, hacked, testMP3StdStreamer.
esdrec | lame -b 128 - - | mp3stdinstreamer
This works quite nicely so long as nothing else is happening on the machine as the mp3stdinstreamer app does no internal buffering and the stream stutters badly when the app doesn't get the CPU time slices it expects.
First thing you can look at is Shout2rtp:
http://minnie.tuhs.org/Programs/Shout2rtp/
Which can, as far as I recall, also stream from files directly.
I have an IPv6 version of it if you need it.
Cheers, I'll have a look at that.
Buffering should be handled in the client IMHO. Or do you mean buffering
while reading the file from stdin?
I'm pretty sure it's the buffering of reading from stdin that's the problem, although this may have more to do with Nick's mention of MP3 behaving very well when streamed (thanks for that, btw, Nick. I'm compiling tooLame as I type).
