hi,
the client sends the queryhit-msg through exactly the same connection back he received the query-msg from. that's all.

clients use a list of a few thousand msg-GUIDs they received, so if it forwarded a query to all their direct connections and 20 seconds later he receives a queryhit-msg, the client has a look on it's routing table from which connection he received a query-msg with the same GUID the QueryHit uses.
