Picture running something like Docker on a box, where each container gets its own IPv6 address—with services on their proper ports—instead of mashing a bunch of NATed ports together under the host's IP.

Or, moreover (and this is a bit of a pipe-dream, but it's something I've been hacking on to make possible) picture running something like an Erlang node on a box, where each Erlang process gets its own IPv6 address, fully Internet-routable. This effectively makes Erlang into an SDN vswitch for ephemeral, featherweight virtual machines (which would be oddly similar to AWS's just-announced "Lambda@Edge".)
