Or alternatively encrypt or at least obfuscate the location
information so only trusted parties can read it. That would be similar
to the intent of tickets in our FAST proposal
(https://tools.ietf.org/html/draft-herbert-fast-00) where data in
extension headers is only interpretable by the origin network. Now
that I think about it, geo-location could be probably be encoded in a
FAST ticket.
