This brings up something else I was wondering about: If you truly strip
down the OS running the nodes so that its just a tiny kernel and only
the essential libraries, the users would have to compile all their
software (assuming they compile their own code, like they do here)
statically linked.

Is anyone here using an arrangement like that? Is that too impractical?
