I agree with this figure -- I mean, it reflects my current understanding
of the architecture.
In my understanding of Glen's explanation during Interim Meeting, there
would be a "HOKEY server" as a separate entity, and both the local
Diameter EAP Proxy and ERP proxy talk to this HOKEY server using this
proprietary protocol (a).

Note that the proprietary exchange (a) with EAP proxy is necessary only
for implicit bootstrapping, which as you know I believe should be avoided.

Best regards,
Sebastien.
