icecast supports relays. See the docs:
http://www.icecast.org/docs/icecast-2.3.2/icecast2_relay.html

basically, you just tell your icecast on B to pull from mount point(s)
on A.

It's not at all a strange situation and is often done to spread
bandwidth usage around. For instance having a master icecast server that
_only_ allows connections from the relay servers. The people listening
to or viewing your streams get it from the relays in this case.

Of course, mp3 is not encouraged by xiph (nor myself).
