some guys from ohm force mentioned at the unified plugin api meeting
on sunday that they and a number of other people on the music-dsp (or
perhaps some other list) have written a 60 page document on proposals
for a plugin API. they left the meeting before i could get a url (they
had a copy with them - this is not vaporware).
it seems like it would be worth reading before going to far further
with XAP.
