So how does DSTM solve this?

I was assuming there would be a v4-over-tunnel cloud and a native v4 
cloud, and obviously some kind of connection between both clouds.

In DSTM there is a single place where this happens: the gateway where 
the tunnels terminate. "4over6" could be more flexible as packets don't 
necessarily flow through a single gateway. We may even provide for some 
kind of "proxy 4over6" tunneling so that IPv4-only hosts in otherwise 
IPv6-only networks may enjoy connectivity.
