I did get some private mail from them like a month ago, about some interest to
get more BSD hackers so
they are not really dead. The specific device driver development does seem to be
mostly closed source.

I wrote that on the original email, as I said it's just FYI. They did do a lot
of work though (I bet you haven't
read the specs ;) )  so maybe their ideas have some space in an evolved OS like
DragonflyBSD, at least as
reference. They claim the real value in the framework is technical, not just
source and binary portability,  and they did a lot of benchmarking on their

The death or life of SCO and the success or failure of it's legal actions
lawsuits against IBM is not something that I care about ;). About the triviality
of developing device drivers, well... UDI is less than a week away of porting
effort  to someone that knows his way around BSD. I guess it's a matter of
determining if it's a better deal for a driver developer to find a sponsor for a
BSD driver or a sponsor for an UDI driver (I have NO idea).
