Hi Paul. While what you say makes sense on INVITE/MESSAGE, does it also make sense on subscriptions? If Alice wants to subscribe to Bob presence status, and a proxy in the patch diverts the SUBSCRIBE to Carol, then the SUBSCRIBE with "To: Bob" arrives to Carol, should she accept it? If so, Alice would see Bob as connected while the fact is that she es Carol. Also, usually presence is managed by a presence server (i.e "presence" or "message-waiting" events), so in these cases diverting a SUBSCRIBE makes no sense, does it?
