So what's wrong with sampling the audio on the AVR, sending it to Random
Host by RS232, then over to beige by ethernet, doing a little processing
and then sending the results back the same way? :-)

Who said that DSP stuff must be done on a DSP?  If Christopher can write
Wolf-3D on a Toad, then an AVR (somewhere around 30 times faster) can do
this.  Don't let the absence of a multiply instruction put you off.  The
Toad doesn't have one either.  (Here's a challenge for you: write a pair
of fast 8*8 and 16*16 multiply routines for the AVR.  You can download a
datasheet for the AT90S4433 from http://www.atmel.com)

OK, maybe not the wavelets.  But these are unusually quick little micros
and I'm sure they're capable of some interesting things.
