> I personally have no issues. My only "concern" is that if we start discussing IDs other than the IPv6 addresses, we might later discuss e.g. layer-7 stuff. Not that layer-2 and layer-7 privacy issues are uninteresting.. but rather than the more focused we stay, the more tractable the problem is.

I would not want to discuss in an IPv6 draft the precise mechanics of changing MAC addresses, or the policy controls to make avoid nasty side effects. I would like to see a simple issue debated: "assuming that the host administrator has programmed the host to change its MAC address before visiting network X, can we guarantee that the IPv6 IID does not leak information about the identity of the host."
