Due to the three month expiry, I doubt that any two clients have access to 
the same set of zones, which would make ACL management pretty exciting, 
particularly since I believe the credentials are stored in some SSO thing 
from Okta.  There's over a thousand zones and there's certainly over a 
thousand users, so we're talking about ACLs with more than a million 

Also, based on some of the chatter here, I suspect that a many of of the 
users do not have the expertise to run a secondary DNS server and manage 
TSIGs.  A lot of CZDS users log into a web site and point and click to 
download files.

Viktor and I can do whatever we need to, but I don't think that scales. 
The automatic scripted stuff is somewhat documented for the daily 
downloads, and not at all for all the other stuff like extensions and
