One thing that you might want to mention Alexander: 9P is not a general
communications protocol. In fact, it doesn't work very well across the
internet at all. To get decent performance, the Plan9 group (which, is a
very cool group. :) has to specify a new protocol that competes with TCP
on the level of complexity (IL: http://plan9.bell-labs.com/sys/doc/il/il.html)
Also, 9P is a general communications framework only in the context of
Plan9 itself. In reality it only applys directly/well to filesystem
related issues... the reason it works well in Plan9 is that _everything_
is a file (part of the beauty of plan9).
With some elbow grease, 9P could probably be made to work in the kORBit
framework. It's not even that big of a deal: it just takes time. Believe
me when I say that IIOP is not a very good user->kernel communications
mechanism. :)
