3. my own anecdata from the IPv6-only default WiFi SSID at FOSDEM conference in Brussels this year is that ~40% of the total devices were able to use IPv6-only SSID behind NAT64 - up from about 15-20% last year. Will be interesting to see the numbers for the next year - with Android 5.0 shipping RDNSS and Apple's move with iOS, this number should go up noticeably.
re NAT64: not so agreed...
1. T-Mobile USA: they have few millions of IPv6-only subscribers using 464XLAT which has NAT64 as a component.
2. Starting from iOS9, every app submitted to App Store will have to work with IPv6 or across the NAT64 as a criterion for appstore submission:
