This doesn't surprise me at all.  We heard about Mach for the Symmetry
when I was working on the systems staff of the local CS dept, which
runs an S27 as the departmental backbone machine.   We started to look
into Sequent's Mach, and what we saw scared us:

1) Sequent said that they would not support anything on that OS.  We
   could not afford to have an unsupported machine as the backbone.
2) No NFS at all.  Another *VERY* negative point for our site.
3) A fairly high cost for unsupported software (the number $15,000
   sticks in my mind.  

Things may have changed much in the couple of years since these first
looks into Mach.  I somehow doubt it, given the rate of change in
Sequent OS releases.

NOTE:  I no longer work for the above mentioned CS dept, and am in no
way, shape or form speaking for them or expressing an official opinion
of the CS dept.  I don't even think we formally brought up the idea
with the head honchos, given the lack of support and NFS.
