I'm not really following this. Users authenticate to domains with passwords
(at least sometimes) but I would expect inter-domain authentication to be
done with TLS mutual auth.

Also, my sense is that authentication is not the primary barrier to
inter-domain calling.


Similar work for HTTP has been warmly welcomed by several people.
