Hi Michael,

Keep us informed if you pull that off... I'm interested in that 
functionality as well, for similar reasons.

For what it's worth, on the torque mailing list I remember that somebody 
had a script for instantiating and destroying a VM on job start/end. 
Can't remember who or what, but it's worth checking out the mailing 
archives for that (sorry, rushing at the moment so no time to do it).
