Ices comes in two flavors,
- 0.x flavor which supports sending an MP3 stream to an icecast server
- 2.x flavor which supports sending an Ogg Vorbis stream to an icecast server.
for the latest version of ices0 hav a look in the svn repository at http://svn.xiph.org/icecast/trunk/ices0/
development of ices2 is split up into two branches right now.

- http://svn.xiph.org/icecast/branches/kh/ices the kh branche of ices2 as several new features and depends on a [modified version of libshout].
one of the new features in ices2-kh is a new input plugin for jack. this way you can send a live ogg vorbis stream from any jack capable audio application.
