I think the right question is: How much local traffic will there
be and is that enough to make local shortcuts cost effective?
Part of that discussion may involve what "local" means.
Things get complicated because current practice is not to charge
by the packet-mile but rather by the size of the access pipe. A
local shortcut might avoid the need for a larger access pipe or give
better response over an existing pipe. So we are still talking real
money, it's just that we are looking through a foggy window.

Does anybody have back-of-envelope type numbers for per-mile link
costs?
What does it cost when I fetch a file or web page from the wrong
side of the country or ocean?
I know the cost won't show up on my bill. I'm looking for some handwaving
estimate of the incremental cost to the whole system.
