Not really.  Maybe about 50% for all the extra bitrates.  Depends on
what your master bitrate is.

Icecast is still not the right tool for the job here.  You would just be
building a lot of glue to make it do something it was just not meant to
do.

What you want is a perl script.

http://www.server.com/music?file=blah.mp3&bitrate=24

which would set up a pipe with lame and send the reencoding file back to
the client.

You'll still need the m3u files, or at least an m3u generator:

http://www.server.com/music?file=blah.mp3&bitrate=24&mode=m3u

etc.

You could even use apache rewrite rules to turn those into:

http://www.server.com/music/24/blah.m3u

etc.
