Randomising MAC address
How on earth is this possibly going to work? If you randomise a MAC address connecting to an access point, how am I supposed to apply DHCP reservations, keep tabs on which machine is which, apply MAC-Addressed VLAN policies, not to mention how this would possibly break captive portal and hotspot-style services completely.
I may be completely missing the point here, some information how how exactly this will be implemented would be extremely interesting to read. I'm going to have to assume they'll negotiate with the AP initially with the real MAC address and then randomise it from that point onwards... This is making my head hurt just thinking about it!
