Hi Nick:

I think what you're looking for is Condor, from the University of
Wisconsin.  They have software that can harvest Windows machine cycles
without all the reboots you're describing.  It allows the use of Windows
computers whenever they're idle, not just overnight, and if Condor is
using a machine when it's owner wants it, it just checkpoints the job
and gives the machine back to the owner.
