I've given this some thought in the past...  I'd like to point out that using 
condor_status to derive the list of execute nodes has one potential flaw:  if 
you're really trying to hit *every* execute node, then nodes that are 
temporarily not reporting in at the time (say, due to a crash) will not get a 
job scheduled to run on them.

Just my $0.02 worth...
