You should look into sun gridengine (http://www.sun.com/software/gridware/)
which has a nice mechanism for detecting idle time and running jobs when
interactive idle time reaches a certain point. You can even schedule your
workstations to become available for compute jobs after a certain time
using their calendar function. They even have an appnote on how to do
what you want to do (http://supportforum.sun.com/gridengine/appnote_idle.html).
We have recently (last few months) moved from OpenPBS to SGE and I must say
SGE is quite nice. It is much more stable for us with our large job arrays.
