We did play with the Pathscale compilers once but the license server
they used caused us too much of a user support pain as it binds
licenses to a user for a period after the compiler has been used.

they've basically fixed that by reducing the timeout. the initial timeout appears to have been modeled on an organization with full-time developers, who would actually keep using the compiler frequently for most of a working day. thus the number of licenses would correspond
sensibly to the number of developer seats.  this makes no sense in an
academic cluster environment, of course, where it's very rare for a user
to spend a long, solid time recompiling.  the current timeouts work very
well for us.  (if there's interest, I can grep some usage stats.)

If they swap to FlexLM we may revisit that.

I hope not.  flexlm isn't terrible, but it's certainly no better
than Pathscale's license server or other RYO LS's like Allinea.
