So we don't want to force networks in the default-free zone to buy bigger
routers with more memory, but it's ok to force them to essentially build a
second network by having redundant pops in every city?

I'm sure the router vendors and colo builders would love this idea, but I
don't think throwing hardware at the problem will help in the long run.
