As a product of having a motorola sb6121 and a netgear wndr3700 both of wh ich I bought at frys I have ipv6 in my house with dhcp pd curtesy of commcast . If it was any simpler somebody else would have had to install it.

Except that Apple Airport Extreme users must have one of the newer hardware versions, that is my experience as well.

And, even before Comcast and new AEBS, Hurricane Electric removed all other excuses for claiming "no IPv6". "Remove excuses" != "Create incentive". There are an infinite number of

Just having IPv6 doesn't create incentives to make their code work with IPv6. People just trundle along using IPv4. Turning off IPv4 creates incentives. Reducing IPv4's capabilities creates incentives. Being told this needs to work and be tested with IPv6 creates incentives. [jjmb] turning off IPv4 is not realistic at this time and there are other ways to encourage the use and adoption of IPv6. Enabling by default, requesting upgrades for existing products that introduce support for IPv6. Enabling IPv6 alone is a significant statement especially when your business relies on the same. The absence of IPv6 or broken IPv6 when your business relies on it are no longer options.

Broken networks get people to fix things. Unfortunately most developers don't test with broken networks. If they did "Happy Eyeballs" would not have happened. The applications would have coped with only some address of a multi-homed server working.
