Most options, like this one, require trusting the user to play along. If 
they don't/won't. Then you can enable preemption and setup policy to 
de-prioritize the user's jobs the more they have concurrently running. 
This is like running condor_vacate_job on their jobs.

Ian can probably give you a handful of configs that do that too.
