Kent, I am curious what else you have seen regarding Plan 9. You may not know, but the Plan 9 files system protocol has been in the main kernel tree for some time, and various other bits and bobs are being slowly ported from Plan 9 to Linux. I will have to check into to if the user defined name spaces have been ported yet -- those are useful. If you are interested in looking robotics using 9p take a look at Styx-on-a-Brick.
