Re: [OAUTH-WG] carrying oauth authorisation without HTTP

Thanks for the feed back. So in our case the communication between the Home
router and the RS is DNS over TLS, so no HTTP, CoAP. We do not have hard
constraint over the protocol being used between the Home Router and the AS.
Currently there is no such communication.

One possible solution would be to have the Home Router using a mutual TLS
authentication to provide its certificate which is then passed to the RS.

Yours,
Daniel
