MAC address restrictions may seem like a nice solution, but the administrative headache is way beyond reason for a larger network. In my experience it's fairly impractical to impliment on larger networks and on very small networks (a single small office, for example), physical security is often sufficient. In addition, we frequently have sales reps or visiting contractors who need access to our network with their laptops, either for work or for presentations. Although our "public" network jacks are few and far between, it would quickly become a nearly full time job just to be adding and removing MAC addresses from the filter. On the wireless side, it's more relevant, but..... it's fairly simple to spoof MAC addresses and to sniff them out of the air in a wireless environment, so even there, it's not a huge deterrent except to unsophisticated "bandwidth thieves".
