This works (although it's lacking a key to distinguish between the machines).

I'm still a bit confused 8( but to summarize:
- if I refer to ClassAd attributes, I don't have to write $(...)
- upper/lower case doesn't matter
- TARGET may be used as a prefix to distinguish between machine and
job classAds - MY.Memory would refer to the job Requirement.
If MY.Memory would be defined, Memory without a prefix would return
that value? Then only ( - TARGET.Memory ) would be ultimately safe :-(
