The problem is really in the beacon frames and how the clients interpret 
it. For instance, XP will not associate with an access point that doesn't 
have the privacy bit turned on in beacons if it is configured for 
encryption (even with 802.1x). On the other hand, most clients won't 
associate to an access point advertising WEP encryption if they don't have 
it on.

So I guess one would need a way to broadcast two different beacons 
(probably with different SSIDs), one with and the other without the privacy 
bit set to one.

Not yet :-( Let me know if you get to anything interesting.
