More generally, when you have a central node (the AP) there's a node
that can carry the accounting, and has the "authority" to say who's
welcome and who's not.

I don't know if 802.11a/b/g/n has a mechanism to reject association,
or if it's a dirty hack with only giving a liminted number of DHCP
leases.

Either way,  ad-hoc peer model isn't well equipped for this limitation.
