I've been trying various concepts over time, but nothing is fool  
proof. What if a customer looses power, everything reboots and he's  
got a new IP from the DHCP server? We won't allow that registration...

I think an external hook that optionally can be executed is better.  
That way, a system could send a warning e-mail to the customer or  
notify him in some way that he's confusing the system.
