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.
