Yep. I agree. If you're not properly implementing the DHCP protocol your device should be blocked, easily enough. They can find the offending MAC addresses and refuse to give them addresses.
I don't know what the problem Princeton is claiming. But if it were something that simple, wouldn't everyone be noticing it? So far my iPad has been through 4 hotels and 6 airports in addition to my house, bouncing from DHCP server to DHCP server, no problems yet that I can see.
