That makes sense. The majority of IPv6 deployment is mobile.

The next wave of adoption requires ISPs start offering residential IPv6. Once this happens, router manufacturers will innovate around the IPv6 offering as a differentiator, making it easy to deploy by end-users. IPv6 wifi APs will then become ubiqutious and so forth across other services. Has to start with ISPs.
