I did not check seriously so I cannot confirm or deny but do note that
there are several proposals to improve "peer selection" behind random
sorting or crude measurements with ping on a few hosts. A summary of
existing work is on the ALTO Web site
ALTO will have a BoF session at the next IETF in Dublin, so we may see
one day a standard protocol for peer selection.
