How about having the server run a validation app full time.  It can  
periodically check to see that it is installed legally on the server  
by checking the MAC address and then generating the appropriate key.   
If they both match as expected it continues to run.  The server app  
is listening to a port where the clients ping for validation from the  
server app on their startup.

On an illegal install, the server validation app will not allow the  
clients to run when they check in on startup.  The only negative is  
that you have to have an app running on the server.  Should not be a  
big deal.
