add to it: forward the DHCPDISCOVER to the DS if no internal table entry for this MAC is found. yapp, that would be even very easy to integrate.
but i don't think that _any_ AP does that.
Well, an AP that does 802.1x + chillispot is all you need :) You get the accounting, bandwidth shapping and traffic limits for free
just for the case: no, it is NOT possible to assign IP addresses by 802.1X; you have to do DHCP after the authentication (yes, it is strange).
A clever AP could support this: 1. Serving DHCP to the wireless netowork only 2. Getting the Framed-IP-Address from the radius Access-Accept, and putting it in a internal table (MAC -> IP) 3. Serving that exact IP via DHCP when the subsciber asks for a lease.
I don't know of an AP that does that, though.
