Beautiful Stranger, As an alternative to an aluminum bat, you could reserve an IP address for each MAC address using DHCP. Then restrict access based on IP address (client set). Maybe if you require users to change their password everyday, they might get the hint.... Otherwise, I'd go with Jims approach.
