Any of the HPC guys who read this list know of anyone using

I seem to remember IBM did somthing like this with back-to-back DMAs in
RS6000 in the early 1990s, but does anyone do it now? or do we feel that
UDP over 40gE is fast enough for anything anyone needs (at present)?

It's funny, it's as if you have the exact opposite vision as I have.
One of my " aha!" moments messing with Plan 9 was the thought that
generic consumer physical layer networks are the "backplane" of hardware
expansion in Plan 9. This is how I've since viewed Plan 9 and inferno.
In fact my first thought was " damn, well now I don't need all of this
pci[e] crap -- just a NIC".
Ever since then I have been in the development stages of some 9p devices
using microcontrollers of various capabilities. I had my arduino
getting almost all the way with negotiating a styx session over ethernet
(no auth). Then I got married..... :) in due time I will get there.
I've dropped the arduino though, moving on to bigger and better things.
I know this has nothing to do with your question, but I just wanted to
share a point of view.
