At some point I played with the idea of including the interface-index (rather than the MAC address in F() (in the algorithm in draft-gont-6man-stable-privacy-addresses), which would still make the resulting IIDs vary across networks as the host moves, but remain constant in the presence of hardware changes. > and one can imagine a prefix-renumbering mechanism that could handle > this.
