[dnssec-key-tf] agreements on the use of the repository

Here are some of my thoughts, as bullet points in response to the 
discussons so far.

TLD only or not: I favor TLDs and .arpa.  Whether or not .apra and its 
children are signed in the wild, I think the TAR should aim to include 
those .arpa beasts.  There's nothing wrong with redundancy -- it can 
even be useful.

Publication format: I agree with Daniel: "As many as are required by 
the users."  Multiple formats are good and I have no strong 
preferences re:  dynamically queriable v. bulk only.  (In particular, 
I'm not going to insist on DLV as a publication format.)

Location: we should be talking about a service to be run by the NCC. 
Even if IANA does (or might someday) run such a service, redundancy is 
useful.

Querying the repository: should NOT require any agreement.  We don't 
want to create barriers to using it.
