All right,  I'm game.   Just for starters I would say that this is 
not a very well balanced system by today's standards.   I am biased in
this statement by a long term involvement with supercomputer Unix
implementations.   More than 200 users implies that you have a fair
chunk of memory.   With this much memory 10GB of disk is probably
inadequate.   50 mips is probably also inadequate.   The Cray-2
at NERSC in Livermore california supports 200 users at a time as
do,  I believe,  the YMP installations at NASA Ames and the YMP
at San Diego Supercomputer Center.   Is this the class of machine we
are talking about?   If so then this is a supercomputer Unix
forum.   Such a forum is worthwhile now that there are other contenders
besides Cray research in this market.
