That's sort of ridiculous -- they're having to reconfigure "each and every" Windows machine on campus. Either that's how the option/feature really works or that they're just worried that enabling that option would allow other non-Cisco cards to ride on the wireless network.

However, working around their policy may result in severe penalties -- for example, being banned from the wireless network. There are ways to prevent forwarding packets from specified wireless cards (they block out the MAC address), so its probably wiser to work with them instead of against them. I'd try to coordinate with Apple and Cisco on this one. Maybe if you show the admins that there is a simple way that doesn't inconvenience them it would work out for the best.
