I was, and then I did. :)

It's in CVS now. I'm doing some cleanup over the next few days and
expect to have a "development" version ready by the end of next
week. It's changed too much to be released as 0.1.1, both in terms of
new features and lack of testing...

For the curious, here's the stuff I've done so far:

* Reencode the same playlist at different bitrates/sample
  frequencies/channels simultaneously for different mountpoints. Just
  add multiple stream sections to the config file or use multiple -m
  options on the command line.

* Read vorbis files and reencode them as MP3 - if you've got the CPU,
  you don't have to wait for your listeners to catch up, you can start
  storing your music as vorbis now. ices even parses vorbis comments
  for title streaming.

* Proper FIFO handling - including reencoding. The only thing you lack
  (obviously) is ID3 parsing.

* A new function for the playlists, get_metadata, which lets playlists
  set the title stream for each track if, say, you have better
  information in a database than in your ID3s. Also you no longer are
  required to define any functions but get_next.

* If ices receives SIGUSR1 it will skip to the next track in the playlist.

* Build system improvements.

* A man page. :)

Future plans include sending different streams to different servers
(not just different mountpoints), and handling PCM/WAV input...
