Clarifying my remarks at the mic...

Using PD in a home network isn't hard.  Use a single delegating router; most obvious choice is the device that received the prefix from the external source.

Every other router acts as a requesting router, and asks for a single /64 for each of its interfaces from the delegating router.

draft-baker-homenet-prefix-assignment-01 has more details.  Read it before you flame me.

*Recursive* PD is, indeed, harder.  Don't do it.
