Not related to the original subject, neither to IPv6 usability on WLANs, 
just a small comment: As far as I understand "AP isolation" doesn't work 
if you don't have a WLAN controller but do have more than one APs. E.g. in 
the following setup

ap1--sw1--sw2--ap2

with "AP isolation" turned on, clients associated to ap1 cannot 
communicate directly with other clients associated to ap1, however they 
can communicate directly with those associated to ap2. Broadcast from 
ap1's clients does also get to all clients at ap2.
