At first glance this looks like a joke. But if you look closer, it looks really workable (well, maybe except those "mandatory NIC-enforced security" bits)

I'm hoping someone will be brave (or stupid) enough to actually implement this. I have a personal ASN number that I'm willing to participate with :)

Big parts of it are copied straight from v6's approach, so it's kind of inevitable that at least those parts would be workable -- because they're workable in v6.

But of course, you might as well just use v6 at that point.
