Software is important for an OS.

VSI should definitely court relevant ISV's.

Synergex would be very relevant for DBL.

But note that it was "... if ...", so it may just
be concerns that Synergex has not said that they will port
instead of has said they they will not port.

It is pretty obvious from their web site that .NET is their
main focus today.

Question is if there is enough VMS customers to warrant
a port.

Does Dibol compile to native? If yes then they would need
to integrate with LLVM backend.
