That would be very cool of BSDI and most likely benefit them too.

Regarding "Lite3" I don't think there will be one because:

1) The CSRG team has been disbanded.  The VM guy and the ports guy are
with BSDI and the FS/VM guy is freelance.

2) David and John are the care takers of the kernel VM in FreeBSD.  Mike
Karels, I think, is the care taker of the VM in BSDI.  Things like how
mmap coherency are implemented are probably a little different.  I haven't
had a chance to look at BSDI's source recently and no one talks about it
on the BSDI lists so I can't be sure, but I think the approach is
different.
