Hmmm ... interesting concept. How small an OS can you get away with
and still have the JVM on each node? Surely you don't need a whole
GNU/Linux stack. Perhaps something like the openSUSE JeOS (Just Enough
Operation System)? Which JVM would you be using? Are the parallel /
concurrent hooks in the JVM?
