In a word, you can't.

Here at the UI, we take the old world approach. We tell everyone
who needs to shut down machines how to check resources via llkob.
In other cases, /etc/shutdown runs quite nicely (I wish it would
throw a message on diskless partners, though).

Any person who is the victim of a node shutdown is given the
name and address of the person who caused them the trouble. We
seldom have repeat customers.
