Icecast - Dec 2004 - relay question again...

http://www.icecast.org/docs/icecast-2.0.1/icecast2_relay.html

As stated in the above link you can do a single relay, yet
is there a way to change the bitrate on the fly while doing so?

I simply want to stream one 128kbps mountpoint on my slower
server, then have my faster server pick it up, and
relay it in 3 different bitrates/mountpoints... what is the
best way to do this (or ANY way? heh), I can't seem to find the
right tool(s).

Thanks,
CT.
