Thinking about the CPE thread, isn't this a case for bridging as a
feature in end-user devices? If Joe's media-centre box etc would bridge
its downstream ports to the upstream port, the devices on them could
just get an address, whether by DHCPv6 from the CPE router's delegation
or by SLAAC, and then register in local DNS or more likely do multicast-
DNS so they could find each other.

This would require the ISP gateway to have IPv6 ND entries for all of
the end-user's devices.  If that is only a few devices, like the
typical SOHO LAN today, that's probably fine.  It is not fine if I
purchase some IPv6-connected nanobots.  Given today's routers, it is
probably not even fine if the average SOHO goes from 1 state entry to
just 20 or 30.  I have about 20 devices in my home that use the
Internet -- TVs, DVRs, VoIP telephones, printer, mobile phones with
Wi-Fi, a couple of video game consoles, etc.  I imagine that is not
atypical these days.
