It has been working well for almost a year now, and the only complaint I've received was that the registrar for Switzerland (.ch) and Liechtenstein (.li) requires SOA records for a domain before they will register it.

use terminal-based clients.

The problem with this scheme is that it's a blueprint for how to engage
in cache poisoning. When you pass along Additional records that claim
that your server is authoritative for '.', you will, sooner or later,
poison someone else's cache. You break other people's servers for the
sake of your own convenience. That's rude, to say the least.
