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?

Regards.
