Nope, you have this backward. The client announces what authorities it
believes *it is*. This is necessary because the server (turned client)
needs to know what authority it is requesting data from (at the very
least to populate the :authority pseudo-header field) when it makes

The flow is as follows:

Client initiates connection to '', and offers H2 P2P.
It emits a CLIENT_AUTHORITY frame indicating that the client believes
it is authority ''
Server verifies the client's IP address against a static list to
confirm that the client actually is ''

I think this represents a problem with the ambiguity of 'client' and
'server'. This should really be saying that PUSH_PROMISE frames can
only be sent on streams that the given peer did not initiate. I'll
attempt to reword with 'dialer' and 'listener' (or something similar)
to avoid the ambiguity.
