world, they're perfectly happen to move it around the world. Hence, moving a file into a campus doesn't mean that the campus has the file and will stop bothering you. I'm pushing an agenda in the open source world to add some concept of locality, with the purpose of moving traffic off ISP networks when I can. I think the user will be just as happy or happier, and folks pushing large optics will certainly be.
With the regular user small TCP window size, you still get a sense of locality as more data during the same time will flow from a source that is closer to you RTT-wise than from one that is far away.
We've been pitching the idea to bittorrent tracker authors to include a BGP feed and prioritize peers that are in the same ASN as the user himself, but they're having performance problems already so they're not so keen on adding complexity. If it could be solved better at the client level that might help, but the end user who pays flat rate has little incentive to help the ISP in this case.
