Hi Brent,

thank you.  This was very interesting.  The introduction to Mach IPC and
memory management was especially good.  I wonder if a shorter variant of
this part of the lecture could be used by new contributors as an
alternative to reading the Mach kernel postscript books.

Personally, I’m very interested in a Single System Image Hurd cluster; I
still have a bunch of unused Sun cluster nodes with x86_64 CPUs, but
sadly there is no high-speed network to connect them all (just regular
old 1G network cards).

In your experience, is high-speed network very important or are there
ways to make it unlikely that memory has to be transferred across nodes?
