So, I'm wondering why you would do this. I regard access points as
insecure pieces of infrastructure, subject to frequent failure and
replacement. Since all encryption has to be done through to the client
anyway, why do [easily spoofable] [unnecessary] auth of the hardware
itself?

(One answer just occurred to me. Are you doing a single-sign-on for
admin rights to the boxes? But it would be better to maintain a single
logon for the box and only manage through scripts or SNMP...)
