A quick and dirty way of accomplishing this would be to add:

APPEND_REQ_VANILLA = (OpSys =!= UNDEFINED) && (TARGET.CondorPlatform =?= "$CondorPlatform: INTEL-WINNT50 $")

To the condor_config of your machines that submit jobs to Windows.

This will prevent Condor from adding a constraint on "OpSys" and run
your jobs on any machine with the Windows version of Condor (they all
seem to have the same string for "CondorPlatform").

I realize this isn't a generic solution, but the "OpSysFamily" would
need to be thought out better in regards to how to support machines
that submit to both Windows and Linux (and other unix flavors).
