[I am speaking as ACME Chair]

We may have a disagreement about whether ACME or EST is better suited to
this use case, but attacking the other person's level of understanding is
not ok.


@Richard - If ZoTrus runs an ACME server, and you wish to see
draft-ietf-acme-client progress, would you be willing to join Kathleen
Moriarty as an author to help with editing the draft? Also, I don't know if
the ZoTrus ACME server is publicly available on the internet, but it would
be helpful (although technically not required for RFC publication) if you
could implement the draft for your client - server environment and give a
presentation at the next IETF about what you learned -- IE does the text of
the draft as it is written now do what you need, or does the text needs to
be adjusted based on what you learn while implementing it?
