Thanks I may *have* to give it a try. It's a compute farm, and we need to be able to provision say 500 servers today to do something then turn them off two weeks from now. Needless to say, no one wants to do this by hand. I am working w/ our internal guys (You know them I assume.) to encourage this type of feature set.
