Nice to see interest about this, it means a lot to me that the three BSD's,
all with their own fun in use, etc, are willing to work together on this
Also, what I am doing with the PDP (here he goes again) is that I am trying
to determine which BSD got which function where and in what version.
Would make an excellent reference for people wanting to get something
running on all three BSD's. (btw, ignore any FreeBSD words in the PDP, I
am currently making it *BSD.)

Sounds like a nice stance, however (not saying you did Warner) it _is_
absolutely fundamental that we, as the three BSD's speaking, put back
ego's where it's technical excellence that counts. Private agenda's never
served someone. So I myself am counting on the maturity of the participants
to discuss technical internals and not moving to ego-talk.
Note, this isn't about merging all the three BSD's back together. It's
merely about making the API not too diverse/different from each other.
(together we stand, divided we fall - cliche, but true)
To clue in the OpenBSD people who haven't been reading tech-kern of NetBSD,
it started when I pointed out to Bill Sommerfeld that FreeBSD already had
an asleep function, which he was about to implement. A good function, but
substantially different from FreeBSD's asleep, that I didn't think it was
a good idea to just let Bill continue without warning him at least, as well
as Matthew Dillon (original writer of FreeBSD's asleep()).
Can we say at least, that the core 4.4BSD functions have remained largely/
almost the same across the 3 BSD's?
Can we point out at least a few areas in which we differ?
Are there differences spotted at hand which can be resolved on short time?

That sounds like a good thing Warner. Any more to tell about this wrt NetBSD
Looking forward to hear from the lot of you,
