The part that is missing isn't the "some ISPs", it's "all ISPs".  Also, 
I don't know of any DNS service provider that offers a product to handle 
delegations from the IN-ADDR.ARPA and IP6.ARPA trees.

I'm focusing on the SOHO customer market with my proposal.

The allocation of IPv6 space with prefixes shorter than /64 is indeed a 
consideration for bigger administrative domains like country 
governments, but on the other end, SOHO customers would be happy with 
/96, /104 or even /112 allocations if they could get them.  (Just how 
many light bulbs, fridges, toasters, doorbells, phones, &c does SOHOs 
have?)  I would *not* like to see "us" make the same mistake with IPv6 
that was made with IPv4, handing out large blocks of space like so many 
pieces of M&M or Skittles candy.
