First of all, I think it's important you don't try to "punish" them 
for trying to be innovative enough to try new things.

This is what the techintegration lists I'm on call a "teachable 
moment".  Changing the configuration is not difficult.

OK, combine this "teachable moment" with some simple firewall/router 
rules for enforcement.  When the people using these services suddenly 
can't get to the Internet, they will come to their building person 
instead of the district person (usually).

If it's that much of a hassle, you can always NAT those subnets - 
I've done it on an OpenBSD box (P200/32MB) in about 15 minutes, and I 
had no experience with *BSD prior to this.  Linux should be just as 
easy.
