Actually Pando does try to localize traffic as much as possible. Not only that we have started the P4P Working Group.

I'm a bit confused by your statement. Are you saying it's more
cost effective for ISP's to carry downloads thousands of miles
across the US before giving them to the end user than it is to allow
a local end user to "upload" them to other local end users?

It's quite possible that I've completely missed it, but I hadn't seen many examples of P2P protocols where any effort was made to locate "local" users and prefer them. In some cases, this may happen due to the type of content, but I'd guess it to be rare. Am I missing some new development?

If it isn't being transferred locally, then the ISP is being stuck with
the pain of carrying a download thousands of miles, probably from a peering (or worse, transit) with another ISP that has also had to carry it some distance.
