Here is how you can do something similar with current ClassAd functionality
for details on the example I used, see 
www.cs.wisc.edu/condor/CondorWeek2005/ presentations/kewley_cclrc.ppt
section on Firewall mirroring.

In each condor_config.local file:
GROUP_SLOW = TRUE
GROUP_DELL = TRUE
GROUP_BLADE = TRUE

STARTD_EXPRS += GROUP_SLOW, GROUP_DELL, GROUP_DELL

then when you need to test in yoru requirements you say:

# Fuzz matching with =?= may be better here: I forget
REQUIREMENTS = GROUP_DELL == TRUE

If you need to substitute the value "DELL" into the expression when it is some
local macro, MY_GROUP, say:

REQUIREMENTS = GROUP_$(MY_GROUP)

Is that any use?
