Over the next number of months there is a serious review in both IEEE 
802 and IETF on this issue and how privacy can be improved. One of the 
WPA suplicant developers is active in 802.11, so eventually this will 
become a feature directly supported.  We have an Apple team member, but 
he has to play things close to his chest on what and how Apple will do 
things.  I expect a couple Microsoft participants as well.  Google will 
also be represented, but again, how knows what Google will do.

We are planning active tests at the IETF and IEEE 802 meetings.  We have 
in the past had special SSIDs for trails (like IPv6only).

Right now you can try SpoofMAC and see if it works on your wifi adapter, 
we would be interested to know.  Our initial thoughts is minimally to 
change your MAC before association.  Don't change it while assoicated!  
If we can, we would use a different MACaddr for each PROBE REQUEST 
(requires WPA Supplicant changes).
