They already need to talk in the worst way but they don't. (Too much desire for
fiefdoms, I suppose.) And I don't see IPv6 forcing the issue. It can easily see
being the recipient of a one-way "in addition to having IPv4 address foo for
domain bar, you now have IPv6 address foo6, enjoy" message.

And they'll arrange it by setting up a relay of some kind. Perhaps
the case we should be looking at is this:
MX IN MX 10 IPV6
MX IN MX 20 IPV4
IPV6 IN AAAA ...
IPV4 IN A ...
