I think what you want to do is "straightforward" flocking.  (I don't
think afs will be an issue)

Look for FLOCK_FROM and FLOCK_TO in the condor_config files of the two
condor_master machines...

(Or you could just have the "semipublic" nodes be nodes in the larger
condor pool...)

I can give you a hand if you want.  Contact me off-list of you want to
get together.

Cheers,
-Jeff
