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).
