yeah, I announced to put a Howto for it online some time ago.  
Unfortunately it slipped up to now :-/

The pain in your case is mostly that you have to set it up on all  
submit machines, which are around the department. Collecting the  
hostkeys for the setup of the nodes can be done by `ssh-keyscan` w/o  
the necessity to login to all submit machines.
