If you're going to do something this screwy, why not install sshd on the WWW 
server and have it allow ssh access from an internal machine.  Then run the 
cron job on the internal machine.  Do *not* allow ssh to go the other 
direction.

In other words, if you're going to automate something to verify the state of a 
system, make sure that the automation is not part of the state that you're 
verifying.
