Agreed... However, where I differ is that I believe it is content and services which will drive the ability for IPv4 to be considered long tail. If all of the content and services were IPv6-capable today, the need for LSN would be very near zero (limited to the consumer devices that need to be upgraded/replaced to understand IPv6.) However, as it stands currently, a consumer would not consider an IPv6 connection with NAT64 or other LSN to be equivalent to what they expect today (unless they're on a cell-phone where they already expect the internet experience to be completely degraded).
