For what it is worth (slightly off-topic in this thread): Approximate
geographic location is already explicitly mentioned in the ALTO charter
("Initially the WG will consider: IP ranges to prefer and to avoid, ranked
lists of the peers requested by the client, information about topological
proximity and approximate geographic locations.").
IMHO, regarding geographical locations, draft-scharf-alto-vpn-service-00 just
suggests something that the charter already mentions.
