Dear Ladies and gentlemen of the IETF.

I was commenting on a Github issue for the ACME-spec with regard to
issuing certificates for subdomains based on proven higher level
domain ownership. As a response I was asked to forward my request
here. And so I will.
The scenario of wanting to issue certificates for specific hosts while
at the same time having a secondary subject (a top level DNS round
robin for redundancy) is a very normal use-case. One example would be
IRC-servers.
My request for the ACME would be: If I can prove I own the top level
domain, I should also be allowed to issue certs for any subdomain
without need for verification of those.
A concrete example of this would be allowing users to connect to
"toplevel.net" (a DNS round-robin), This can resolve to a number of
hosts. Let's say this resolves to an IP which is also equivalent to "host-
a.toplevel.net". For a user to be able to *either* use the DNS round-
robin or a specific host, that host need a certificate which can cover
both these DNS names. Same applies to "host-b.toplevel.net", "hots-
c.toplevel.net" etc.
Certificates for a redundant setup like this cannot currently be setup
using letsencrypt and ACME, because both domains cannot be verified on
the one machine running the ACME client.
Without support for this, I'm forced to use StartSSL for my cert needs
(as they *will* issue certificates for any subdomains of a domain I can
prove ownership of).


 (For those curious, the full github issue and related discussion can be
 found here: https://github.com/letsencrypt/acme-spec/issues/104)

Thank you for your attention.
