And the bandwidth is only a tiny fraction of what you would need for even low-quality audio.

To be picky that's not true for high-compression formats like Ogg Vorbis (48kbit/second - and yes I mean bits not bytes).  And its pretty good quality...  Of course the issue of compression/decompression isn't something you can gloss over!

The drivers/libraries from the jeenode work great on normal arduino type boards, I've played with them a decent bit.
He (the jeelabs guy) makes a breakout board for it now too, much nicer than having to convert to 3.3v and solder tiny wires on little pads.

Did you include both the rfm12b library and the ports library?
The rfm12b lib requires the ports lib to function.
