I skimmed what I could find immediately on 9P:
http://www.cs.bell-labs.com/sys/man/5/INDEX.html and came to the
conclusion that what I proposed is lower level and more general (it's
also simpler but, given that it's not doing the same thing, that isn't
really significant).

You could implement 9P on top of my IDC API proposal---and this might
very well be a valid thing to do given that some sort of higher level
protocol is required---but, with what I proposed, you could also do
things like implement a stack of software I/O virtualization functions
and send the bulk data between the top of the stack and the bottom
without going via all the components in the middle.  My 10 mins of 9P
experience indicates that 9P doesn't have anything like that.

Or does it---any pointers to good 9P documentation?
