I haven't done it, but I know that one pitfall is that PBS doesn't
like down nodes. You need to have a daemon mark them "offline" when
they're going to be off.

Another way to power a node down is using an external power switch,
some of which talk to ethernet. That's more expensive than wake-on-lan
these days.
