Moab does this by calling IPMI scripts and being able to
track the state of the node via that mechanism.

With Torque you could conceivably have a program that just
paused the scheduler, spotted nodes that were unused and
(if there was nothing waiting to run) powered them off
(either via "ssh $NODE poweroff" or with IPMI).  Of course
it would need to be able to reboot them when there were things
waiting! :-)

cheers,
Chris
