not yet.  we're waiting for a lab full of g5 hardware to arrive.  our g4's
are too slow (dual 533 and 733mhz machines) for the tasks that we'd like
to carry out.

it almost certainly depends on what you're doing and how much programmer
time you're willing to invest.  look at the ParallelR pages, and
especially the rscalapack stuff.  high level, lets you do factor analysis
and principle components analysis on a cluster.

Have you tried Quantian?  bootable linux cd images of R and related
stuff...

Dirk (the quantian packager) , are you on this list?  :)
