Duh! I should have thought of that. Guess I got spoiled having other
people to do sysadmin stuff :-)

LAM can run as a module? Neat!
I was thinking more along the lines of "Now I'm working on project X,
they use MPICH... oops, gotta do a quick bug fix for project Y that uses
LAM with Intel compiler..." so if I had something in the run scripts for
each that could tell all the machines to set themselves up appropriately,
I wouldn't have to waste my limited brain cells on remembering that stuff
:-)
