The RIRs would likely use the NRO as their vehicle so that there's one
central authority. But even if it was possible to get past the
appearance of a money-grab by the megacorps, sorting out the payment
dynamics would be a public policy nightmare of the first order.

That rather goes against human nature.

As crazy as it sounds, this is probably the most realistic scenario
I've heard for deploying a LISP PTR: a small edge organization deploys
it to adjust some completely unrelated traffic factor. Perhaps they
even use it to justify peering in the first place: we know we'd
normally come in shy of your qualifications Mr. Tier1 but if you add
us as a peer at your convenient data center, we'll take care of this
whole LISP PTR thing for you.

Its a hell of a thing to hang a critical-path item on.
