This sounds very interesting.

Would there possibly be a way to compile pd to use Steinberg's ReWire 
system?  This would allow us to use it directly with sequencers like 
Cubase, Nuendo, and Reason in WinNT and Mac.

Thanks for all the hard work.  I think many of us would be very interested 
to see it.
