Enabling IPv6 support for IPv4-only apps on Linux

I think you underestimate the complexity of deploying a new protocol like that.

Also, you know NAT64 exists, right? You can have a v6 only network connecting to v4 hosts. Is that not enough compatibility if you don't want dual stack hosts?

I can't tell you the man-hours, but I can tell you it'd be easier than ipv6. And yes I'm aware that you can give a "v6 only network" a v4 address, which means you're still on ipv4.

(ipv4.1 could also be implemented using the ipv6 header, btw)
