What's the transition plan, if these IXs don't exist now?
Are these IXs required by law, by policy, or something else?
Are they privately-owned monopolies, or publicly-owned

I hear a lot of support for settlements from telcos,
some from governments, and little from network people.
It effectively drives hosting companies out of business,
if they have to pay for transit (settlement for inbound
traffic) but carriers get to charge at both ends of the

Is there evidence that this model provides a network 
that is better, faster, or cheaper?

If economists set addressing policy, can network engineers
set monetary policy?

Because those providers are inferior.  The phrase used
to be, "What's good for the Internet is good for UUNET."
That's tongue-in-cheek, of course.  However, the same 
company owns UUNET and MAE-*, so there might be some
interest, but I think having a single point of failure
(nuke the IX) in each geographical area sounds contrary
to good internetwork design.
