Thanks, Roland.  Interesting draft.

Couple of first reactions:

- Why use the target of the PTR instead of just provisioning the TXT record
directly in the reverse DNS.  (Is there some restriction in the spec for
reverse DNS that says it's only PTR?)  It seems like by using the PTR
target, your security analysis gets much more complicated.

- For the re-use of "http-01", you should probably specify the contents of
the Host header.  (Main ACME should probably clarify that for DNS, if it's
not clear already.)
