Widely deployed Filters, including uRPF, would probably qualify as this
right?

I'm going to show some (alot?) ignorance here... BUT: won't the network
go: pure-v4 -> v4+v6 -> v6 (probably with v4 tunnels) -> pure-v6

I don't think its just going to go: POOF! one night, nor in one year...
Judging by how long it takes people to upgrade a simple major application
or OS it'll take YEARS to upgrade entirely to pure-v6.

of course, I could be completely wrong.
