Re:Enabling IPv6 support for IPv4-only apps on Linux

We did map existing v4 addresses into v6. They're not two totally separate networks at all.
But the limitations of v4 and of existing v4 devices limit the ways that can work. Reinventing stuff and calling it "4.1" won't change that. You'll still face all of the same limitations.

That's basically the transition period that _is_ happening, except we aren't delaying the "open up the new addresses" stage -- the new addresses are usable straight away for anything you've migrated.
