I don't understand. HTTP traffic is typically lopsided
outbound from the server. Are you suggesting hosting
companies would charge more per inbound bit than carriers,
or that they'd develop new traffic/business models? Or
did I misunderstand which direction pays whom?

No more cold-potato routing. OK.

Maybe we should just give very large blocks to exchanges,
which they could assign to customers for regional use. In
addition to current policy.

Ehh, yeah, but they'd have a good shot at being first mover,
or beating competing IX-builders based on name recognition.

Yes, that's a good point. I'd like it to scale, and I'm
wondering if there's an intermediate position where there's
a regional aggregate but non-IX-ians leak more specifics.
Need to sit down at a whiteboard for a few minutes on that
one.

I misunderstood you then, and thought you were advocating.
Is anyone formulating a proposal for geographically-based
allocations/assignments based on this discussion?
