PI solves the majority of the renumbering problems quite nicely and is readily available for
most orgs. now.

Beyond that, I think you will see firewalls become much easier for the average person to
manage and it will become a simple matter of making an http (hopefully https) connection
to the home gateway and telling it which service (by name, such as VNC, HTTP, HTTPs, etc.
from a pull-down) and which host (ideally by name, but, may have other requirements here)
to permit.

Some firewalls already come pretty close to that.

There is also talk (for better or worse) of having something like UPNP, but, without the NAT
for enabling such services.

No rendezvous server required.

I'm still hoping that we just don't have NAT66 box builders. So far, it's working out that way.
