Starts to sound like Rocks.  Which I'll finish installing on a small 
cluster tomorrow and will form more opinions then.  First impressions 
(really second: I've had another small cluster up with it for 3 years) 
is that it's seamless for the scientists once they figure out where 
their apps are.  I've been pretty happy with it: It's been mostly "set 
and forget".

Bogdan, we're in a similar position, save I also do some of the science. 
  Our latest cluster serves users in Atmospheric Science, Chemistry, 
Math, Statistics, Agriculture & Life Sciences, Computer Science, 
Oceanography and Nuclear (or was that "nuculeer"?) engineering... Most 
are somewhat astute to computation but not one rises to the point of 
"computational scientist" in being able to combine extensive computer 
science/engineering knowledge with their much more important discipline 
knowledge.  Hiding the details from them, but meeting their needs at the 
same time is a constant challenge.
