Actually it has been *extensively* addressed (hah, pun) by "the people
leading the IPv6 push". It is not only surmountable, it has been very
thoroughly surmounted, and has been for many years.

There are no less than six standard ways (and anyone can dream up
whatever non-standard ways they like, harmlessly) of generating
addresses on hosts, plus static addressing, of course. Of those five
methods, only has built-in privacy concerns.

 - static addresses
 - DHCP addresses
 - MAC-based autoconfigured addresses
 - random addresses
 - random, changing addresses ("privary" addresses)
 - random "stable" addresses (always the same on the same network) 
 - cryptographically generated addresses

If anyone wants the technical low-down I am happy to provide it (already
been through it once on the provacy mailing list, and the situation has
actually improved since then - privacy addresses are preferred
(technical term) by default if in use, and "stable" addresses have been
invented.

Regards, K.
