Governments are unlikely to force this issue.

However, what I think will happen (and I wish I had the hardware skills
to build the device) is that someone will come up with a compact, cheap
(think price of Raspberry PI) device with two 100Mbps ethernet ports.
One will be an RJ45 plug and the other will be a socket.

The socket will support POE for powering the device.

The device will have a small linux kernel and provide DNS64/DHCP4/NAT64 services
to the RJ45 plug and the jack will connect to the IPv6-only port in the house.

The software is already completely available as open source. There’s a tiny
bit of integration to do.

If you do this for IPv6-capable services on the outside and don’t need to connect to IPv4
laggards, this is a relatively simple solution. If you need to preserve IPv4 connectivity to
the outside world, it gets a little more complicated, but not a lot.

I’m betting that if someone offered the device I suggested above for a price point around
$40 (add a small amount of money for a cheap POE injector if needed), it would do the
trick.
