Argh! Sorry, too many windows open at the same time -- pasted
email and USENET posts in the wrong windows (so, now I have to
go explain an "odd" email to several people.. :< )
AIOE apparently doesn't support cmsg's (?)

Greetings!
Sorry for the delay in writing. It's been busy with "visitors",
lately. <frown> It was good seeing all of you -- looking forward
to April!
I made the Doppler additions to the demo you saw. You should be able
to play with it on your existing hardware. There's a ReadMe that
explains the controls.
I started porting the OS to a small ARM development board. Goal is
to make sure there are no big "gotcha's" before moving the designs
to foil. Having to redo *one* would be annoying; redoing ALL of
them would just be depressing! :<
I've also been reexamining the VM scrubbing code. The synchronous
implementation may be more deterministic but it seems like it's
less *efficient* (well, you know what I mean...). I may try to
move that to the Dx thread at some cost in *real* efficiency
(though a net gain in *perceived* efficiency). I will explore
the options as I port that bit of code to this development board.
[Though I still consider the Dx thread somewhat dubious... OTOH, I
can't see any other way around it (besides the offline option we
discussed -- and it's drawbacks!)]
I also updated the _MMU Exploits_ document in an attempt to make it
more specific/pertinent by eliding those items that aren't directly
used by the OS. Comments welcome. (it still retains a "general"
tone so I will need to make it even more *specific* -- with concrete
examples per *this* implementation).
Watch your doorsteps -- dropping a box of goodies in the mail to
each of you this afternoon. I'll leave it to each of you to sort
out how they get shared in your families -- or not! ;-) I imagine
kiddies will be disappointed (but spouses, not! :> )
Let me know if Vegas or SoCal in April. I'd also be happy to let
it slip to May (all the recent visitors have me WAY behind! Still
a few more "obligations" to address before I can get back to life
as usual...). Much later than May would probably invalidate Vegas
as an option (?)
Good seeing you all!

P.S. Managed to harvest the Valencias the other day. Some 160 pounds
on that one tree! Already juiced about 7 gallons and still have
several bags of fruit left. But, *nowhere* near as sweet as the juice
from the Navels that you had while here.
