It is relatively easy to change the MAC address on some NICS, but some (cheapo off brand) NIC manufacturers invent their own. Also, the MAC address on routers and firewalls can easily be changed. I set the MAC address on my cable modem router to the same as my PC so I can easily plug the PC into the cable modem in the case where I must deal with the customer service droids. Normally, you can asume that the MAC address is unique.
