I believe a SOAPFault envelope can be sent with headers included, but I don't think I've ever actually seen that happen.
The reason why the fault message is only sent to the immediate sender is that 1) the ultimate receiver may not have any means to send the message to anyone else but the immediate sender (with which it has a TCP/IP/HTTP connection open), and 2) because the fault may be caused by something the intermediary did but that the original sender is not aware of (and can't do anything about it). Remember that the intermediary can (and mostly does, I think) forward the fault message upstream to the previous intermediary, its previous intermediary, and eventually, the original sender.
