Network Shutdown

I used Novel Netware a little while ago, and I saw that it had a
feature where you could shut down computers at the admin's will. I've
been looking for a way to implement this in linux. My network is a
bunch of thin clients with a readonly root mounted over NFS, and they
all use LDAP authentication to log in the users. The way I have this
implemented now, is to check the LDAP server. It looks in a specific
directory for a 'command' class, and if the host matches, it executes
that command. I have the script running in a crontab every minute, but
this seems to be a bit messy to me. Is there some other way to do it?
Like making some central daemon they all connect to, and then check for
something similar to a magic packet?

ssh user@hostname sudo shutdown [ -r ] now
