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. Regards, Mike Hancock
