I would hope my last emails start to address this point. The single most
impediment I see to deploy IPv6-only networks is the combined effect of the
2 long tails: on one side, the content is today mostly IPv4-only accessible,
making it a disincentive to build v6-only access network, and on the other
side, the apps are for the vast majority IPv4 centric, making it a
disincentive to offer content over IPv6, to build an Ipv6 capable device
that cannot use those apps or to build v6-only access networks in the first

This realization was the starting point of the development of the DS-lite
