Feel free to explain how SLAAC should work on a /96 with 32 bits of host address
(or any amount smaller than the 48 bits most MAC addresses provide).  Remember
in your answer to deal with collisions.

It's one thing to say "it should be redesigned". It's another matter entirely to actually
come up with a scheme that doesn't suck even harder than "screw it, it's a /64".
