Doak,

I'd be very interested in hearing how you're changing
PREEMPTION_REQUIREMENTS. I'm doing something very similar and have run
into a few issues. See the threads with subjects "Default User priority
factor", "When do machine RANK settings apply?" and "about scheduling
algorithm in condor and condor-g" for some background on what I am
trying to do. Does that look familiar?

Cheers!
