I made my comment in the context of a possible interface collision in
your diagram.  Those had to do with the autonomic nodes, not the
proxies, as I understand things.  To avoid those sorts of collisions, it
seems like using the h/w address remains sensible.  A collision in those
circumstances would be extremely unlikely, whereas relying on poor PRNG
almost assures it of happening.  These devices are likely to have very
little entropy available to them.
