You can reply with OK autentication at user request, and send deautentication when Radius response arribes with "No Authorization", some milisecons later.

Great, we are working on a simple IAPRP (Inter Access Point Roaming/Routing Protocol). Not a general pourpose routing protocol, only to be used to anounce L3/L2 relations, needed to update L3 (IP) routes in the backbone when you receive a L2 reassociation request.

Our idea is to have CIPE/IPSEC/* tunnels between adjacent AP's, announcing (a la RIP) the associated stations (MAC+IP), and new associations when DHCP (server or relay) assigns IP address.

Backbone updates will be done ussing OSPF (zebra).

Like you, I'm waiting Jouni finish driver changes.
