Well, I was thinking/planning on doing the usb side as userland.. since
we have the ugen driver in userland, and most of the work should be able
to be done in userland, so it's less risk of running into kernel issues,
(and supporting new devices w/o having to load a new module)..

I was thinking of using asyncio to get around the blocking issue...
I fixed one of the issues with the code recently, but plan to try to
put it through it's paces soon...

Cool.. :) I'll keep you in mind..
