I agree. I regularly ask my vendors when IPv6 support is coming. All of
them, from ComTrend to Zoom to 3com to etc. have stated that they are
not even started working on IPv6 yet. They all plan on it, though, for
what that is worth. The closest I've found so far is the soho boxes from
cisco. Not really aimed at the residential market, however.
Business-level service is supported now, of course.

We will probably disagree about this one. I will probably give out /48
to residential broadband when we expand IPv6 to residential. But dialup
users typically have zero networks; not even the single LAN of res
broadband. The "CPE" is the laptop (or PC) they dialed in with. ARIN
says "/64 when it is known that one and only one subnet is needed".
Not that changing "all" of our IPv6 dialup users would take more than a
couple of calls :). Talk about a narrow niche.
