How does that get you to the 50% of the Internet that isn't on IPv6?
Are CPE vendors going to provide code for those gateways, or are 
ISPs going to write code and take support calls?

I strongly recommend that every ISP look at its customers' favorite
sites and find out the IPv6 plans for each of them.

You think IPv6 service will be comparable to Internet access with
unCGNed IPv4?

I complete agree, but I think Tony's looking for more detail.
Do home gateways need to support both SLAAC and DHCPv6,
as both a client and as a server?  Do they need to provide stateful
DHCPv6?  Do they need to be DNS servers, or relay dDNS
updates?  If somebody daisy-chains a wi-fi router behind an
edge gateway, how does it get a prefix delegation from the 
gateway's prefix delegation?  

In other words, people need to be deploying IPv6 now, so they
can find out what they don't know, and have time for vendors to 
fix bugs in features they need.  Simply ordering a heap of IPv6
and expecting to be ready isn't enough.
