If a couple of large carriers set their own flag dates, and
turn off v4 at that point, it will be effectively enforced. Plenty
of people aren't particularly 'local' pockets of control.
You don't need an enforcement arm -- it just needs to stop
making economic sense to support two parallel networks. Since it's
automatically wasteful, once enough of the traffic is v6, that may
come sooner than you realize.
Or, just start charging an arm and a leg for v4 transit until
people take the hint...
