Doesn't that assume that the other server will never be compromised?  I 
realize that trying to guess how the other end might do bad things is a 
rathole, which is why I don't want try to invent anything beyond what we 
already have for dealing with downloaded files.

It seems to me that the clever bit about ZONEMD is that it uses the 
existing DNSSEC keys so you don't have to invent a new key management 
scheme.

PS: I agree that a paragraph or two about other ways that people 
distribute zone files wouldn't hurt.
