[PD] Pd on ARM devices

i figure it won't be too long before nearly everyone including planet CCRMA
has a build going specifically for the Pi. there' s a very good chance the
Pi Foundation can license the design to other makers, so by May or so i'd
bet a number of different places will have them in stock. the biggest issue
for me is how much DSP performance you get out of something whose speed
matches the iPhone 3GS. the awesome thing would be to put their display
engine to work doing DSP but i think that's a long way down the line if
ever due to the limited API access. i started a thread about this a bit ago
and if i remember, the falling down point of ARM was that it didn't handle
floating point well. i'd be curious how much these devices could be pushed.
