Comment (by gdanezis):

 I concur that restricting the exit relay on the basis of the entry relay's
 location leaks information. An adversary that may force a user to open
 multiple circuits will be able to observe many exit relays, and by
 omission would may learn the location of the entry guard or guards (as
 suggested above).

 Furthermore, it is not only the location of the guard that is only
 sensitive but (a) the location of the client and destination and (b) the
 network links traversed between the client and the first routers, and the
 last router and destination. The extensive work on AS-sensitive selection
 might provide a guide on how to deal with those, but I am unconvinced
 there is a consensus on how to best chose those under dynamic network
 condition and partial information about the topology.
