Lock/logoff/disable Apple Mac if network cable unplugged

Can anyone think of a way to lock/logoff/disable an iMac when the network cable is unplugged or it loses network connectivity?

Our students unplug the network cable in an effort to stop remote control and avoid managed preferences.

Running OSX Snow Leopard

Any help/ideas appreciated!

The above link shows you how to launch a process when network status changes.  You can then launch a script to do what you want using launchctl when the network status goes to down - and likewise restore everything when they plug it in again.

The second script says there's a syntax error somewhere on this line:

if [[ -z $1 ]]; then

Expected “,” or “]” but found unknown token.
