What we plan is to "avoid having to answer that question" - that is:
we expect to run our servers dual-stack for a long while to come.

Server networks tend to burn lots less IP addresses than client networks
(if you only dual-stack the "internet face" of the platform, not the
tens or hundreds of backend machines behind the load-balancer), so we 
assume that this will work out.

NAT64/DNS64 isn't actually going to help much here, if the client network
is IPv4 and the server doesn't have IPv4 available - the SSL service
has to be given an IPv4 address, be it proxy or IPv4-side-of-NAT64, and
if you have none, you can't solve this without the help of an intermediary
that's dual-stacked...

did you enable IPv6 on something today...?
