From what I hear SCO is not going to use V4 code because
of the changes needed. That I understand and can agree with
them. 

As for OSF/1 in the future...
I can see SCO going with Mach very easily!
Mach is a very interesting system because of the way
it is designed. It is not really UNIX at all. It is a
memory manager and IPC manager (basicly) and a Task
manager. 

The overall design of Mach allows you to make it into
ANYTHING you wish! If you want to run DOS on it, you can 
(what a waste though)...

What I could see SCO doing is creating seperate environments
that run under Mach that are Xenix and UNIX emulators.

CMU already has BSD running on it and they can even 
run Mach native code with BSD 4.3 code with any other
code you want sitting right next to it running all in
parallel! (or serial if you only have one processor).

So what you would have is a Xenix Environment,
UNIX V3.2 environment, and maybe even UNIX V4.0
in the future. This would actually make it EASIER
for them since they would actually break up the now
HUGE UNIX kernel that they have into small seperate
environments all working under the same scheduler!
Thus if you never use Xenix programs, you don't NEED
to have the Xenix system in memory at all! Same for the
DOS emulation! 

I may be crazy, but I think if they go with OSF/1 and
Mach (which is what it SEEMS like they are moving towards)
you will see a MUCH faster and better system than anyone
has seen sofar!

You could even have the C2/B1/B2/D security services as modules
that you could CHOOSE from. If you want C2, you have it. If ytou want
B1 you have it. Their code would not change very much since it 
would all be done OUTSIDE the actual Mach kernel but inside
the UNIX/Xenix/DOS emulators!!
