Interesting.  Would a change to Coyotos mean moving from a
non persistent capability base for the Hurd to a persistent
capability base?

It sounded to me from what I read that the Hurd had been using
Mach IPC.  As I recall the Mach IPC mechanism has some support
for a separate bulk data transfer mechanism (reaching a bit into
old memories).  How interchangeable are these underlying IPC
mechanisms and the capability communication facilities that
they provide?

R.e. "the effort seems stalled" - what is driving (or not)
the Hurd development?  Are there any waiting customers or is
more of a "just seems like the right thing to do" sort of
effort?  (Sorry to ask you Jonathan, but I can go off after
I exhaust cap-talk sources if need be).
