Sure. But, basically this is using DHCP to implement something very much like
IPv6 privacy addresses, isn't it?

There are ways to engineer all of those identification needs into a network, I
think. Some of them may be quite hackish, but still.

Also, presumably keeping logs a few days would allow you to solve most problems
due to compromised system, yet still prevent most privacy violations.
