e2e IPv6 is the goal, nobody argues with it. However, China Telecom said they would put 100+ million customers in the next 3 years. Obviously neither they would get 100+ million public IPv4 addresses nor all the services in the world would be IPv6 ready. Yes 6->4 may not be an immediate problem we try to solve, but IPv4 exhaustion problem is immediate. I guess we are all here to find out the real problems and give guidelines to solve the IPv4 exhaustion problem and deploy IPv6 in parallel.
Sure, and this seems like exactly the use case where you might
need PT (6to4), since as you say, you need IPv6 to address the
10^8 hosts but those hosts will want to talk to some non-zero
number of IPv4 services.
