I tried this with Mosix.

Problem is - mosix migrates jobs after a while. Initially a compiler
takes up a few megabytes of memory, but "after a while" it has grown
to hundreds of megabytes. When mosix decides to migrate the compiler
it will spend a long time on the netowrk to move the large process
image.

There's some patch to make that integrates it with Mosix, but I didn't
try that out.

Instead, I implemented  http://unthought.net/antsd  which will distribute your
compilers efficiently to the proper nodes.   It's not very sophisticated, but
it does the job for me at least  :)
