One way around to ease the management burden in this kind of setup
is to have your AP's communicate with either central or distributed
RADIUS servers, in order to determine if specific MAC addresses should
be allowed to associate with the AP.
Actually I'm not sure if you can do this with the Cisco 802.11b kit,
however it is certainly possible with many other vendor's kit.
There is a white paper on this at :

( http://makeashorterlink.com/?K22A159A6 ) in case it wraps!
