This way users won't be able to do so, and even in the event they try to boot with some sort of "live Linux CD" and change the MAC, this change won't persist after reboot. If you prefer/need to control this changes from your Linux box, then you can play with iptables and its "mac" match (to bind together IP/MAC pairs) or install "arpwatch". The latter won't prevent users from (maybe) succeeding in their attemps to gain access to places where they shouldn't be allowed to go, but you will be inmediately notified if someone is not playing nice in your network.
