Valuable thread, thanks everyone.

What's the scope for session-MACs, i.e. a new MAC generated and used 
each time an 802.11x network is fired up.

As I understand it, the MAC does not functionally need to bear any 
intrinsic or permanent relationship to the device - it's merely a 
reliable identifier within that space during the period the network 
is operating.

(Ah, yet again I can argue the need for entifiers to distinguish 
entities, and identifiers to distinguish identities, with multiple 
identities per entity).


Another angle entirely:

Isn't the wavelength(s) that 802.11x work(s) on getting a little crowded?

Personal Area Networks were originally thought of as being 
Bluetooth-based, which would have been in another band, wouldn't it?
