Given that the point of this PI exercise seems to be to increase the
viability of IPv6, maybe you should go for it, and add number portability
too? That should further increase the viability.

And the current group has a superior grasp of the all-around picture? Ah, got

Since there's no technical difference between PI and number portability, I
expect approval of PI-space will lead to portability anyway.
Yes, the current criteria for PI-space are rather limited, but since there's
no particular technical rationale for picking /N versus /M, I expect to see a
salami-slicing political debate in which people will demand smaller and
smaller blocks be supported, because to do anything else is dumping on the
"little guy", while letting the "big players" have acess to something the
small players don't.
Sigh, we're going to be paying the price for not (long ago) setting up a
charging system for having a route be visible in the "default-free zone".

I'm curious to hear what the ISP's will have to say about this "topology
constraints" stuff...
