Not to toot our horn here, but our position paper [1] provided
what we think is a good literature review on application layer
topology estimation -- from synthetic coordinate systems like
Vivaldi, PIC, and GNP to the more recent work on Ono, which uses
Akamai CDN servers to fine tune peer selection.

By and large, the conclusions we arrived at following the
literature review were summarized aptly by Enrico in an earlier
email:

   I think the IETF should focus on the first part of the
   problem, the front-end of a generic third-party peer selection
   service p2p applications can query in order to make better
   choices; innovation and competition will then happen on the
   back-end of such a service without requiring standardization
   in the first place.
