I think Cullen has a concern about the following text: "If a registrar receives a REGISTER request containing a P-Asserted-Identity header field, it MUST disregard the asserted identity unless received over a secure transport from a node within the Trust Domain. Otherwise it MAY use this as evidence that the registering UA has been authenticated as representing the identity asserted in the header field." I think we may need to delete the second sentence.
