They share code but Open split from Net over 5 years ago. Only a NetBSD
person would consider it still derivative of NetBSD. :) Obviously a lot
can change in 5 years. Open *really* emphasizes security over everything
else... this may include practicality and usefulness from time to time
:).

I don't think that the tadpole support in Open is derived from Net's... I
could be wrong there though. Things are borrowed in all directions in the
*BSD world.

Like you said for Net:

This is true for Open as well except that bpp does appear to be supported
(it's found). I have a dmesg laying around for the 2.8 release that may
show you what *is* supported. :) My SB is sitting at home off. I'll send a
dmesg from -current if there's any change in supported devices.

This is a 3GS, 32MB, 1.2GB disk. The device names would be from
OpenBSD. They should be recognizable though...

AFAIK BSDi remains a commercial product and is not free. BSDi has always
been a winner on i386. I'm not sure where it will go on i386 with the
acquisition of Walnut Creek CDROM (home of FreeBSD CDROM's among other
things). I believe JKH of FreeBSD is working for BSDi now?

dig around in http://www.daemonnews.com and look for the BSDI/FreeBSD tree
merge initiative stuff.
