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.
