Yes.  the ITC (creators of Andrew (window manager), AFS (Vice filesystem)
uses the vendor-supported variants of Unix as a base, which creates some
interesting conflicts:  (Ultrix 2.2 vs. 4.3BSD, RT Mach (4.3) vs. AIX, and
SunOS vs. Sun Mach)

Yes, mostly.  There are some small remaining wierd hangups, dependent on
the binary.  SunOS features like NFS, SunView, RPC, and quotas (which aren't
generally used in the CS Dept.) are not standardly available here.
It is now believe that Suntools will run, although the Mach Sun in my office
won't quite do it. (probably a missing file)  X11 has never had a problem.

Mach binaries run easier under SunOS, for example.  Saves me from porting a
lot of miscellaneous utilities:-). just cp /usr/cs/bin/wh /../sun/usr/cs/bin/

DISCLAIMER:  I speak primarily as a Mach user and SunOS maintainer, not a
Mach developer or anyone in a position to implement changes and make them 
stick. (This may change as our group converts to Mach.)
