As a security measure, however, Mark, this (MAC address filtering) is 
relatively weak. Some basic sniffing will reveal the associated MACs (which 
traverse the air in clear text). After that, it's simply a matter of 
spoofing one to get connected. Obviously, if there's already an IP assigned 
to that MAC, there will be some connectivity issues, but when your 
legitimate hardware is offline, someone else may freely connect (and you'll 
become quite frustrated with your on again/off again connectivity).
