There's a package out there called sleepy cat - or something like that which
is about authenticating MAC addresses and maintaining access lists I think.
Not sure if it would help here.

I agree. Access to my APs is not free, so you can see why I am
interested in MAC filtering. I realize that someone could sniff a
subscriber's MAC address, and then use it to gain access to the AP.
Fortunately, anyone in this area (read: technology dead zone) that knows
how to do it and would actively seek out hot spots, is probably already
a friend of mine so the issue isn't a big deal to me.
