Agree with all that you say. Only that the "P-Preferred-Identity:" is optional. If it is not present, the proxy should add a predefined  P-Asserted-Identity: header field, if it is going to send the request to a trusted node.

But as you can see, this implies different possible cases. So it would be very nice if we can do all of this using some module or something like that, don't you think so?
