Icecast can handle the extra stream, but it can't generate it.

I recommend StreamTranscoder for doing this.  StreamTranscoderV3 was on 
OddSock.org which no longer hosts compiled binaries.  You can still get 
the sources from the Subversion repository at 
http://svn.oddsock.org/public/trunk/streamTranscoderv3/ which, depending 
on how you are with compiling things, may or may not suit you.

There's absolutely no documentation for this program, but I wrote up steps 
on how to configure it back in February 2006. 
http://lists.xiph.org/pipermail/icecast/2006-February/010295.html

I've been using it successfully in a number of settings ever since.  I've 
not tried AAC with it, and some search results suggest that you might need 
to apply a patch to the configure script in order to get it to work, but 
that patch is easy enough to find.  I plan to play with this myself 
shortly so I can post back here if this is of interest to anyone.
