Ted, I didn't think it was relevant, but I read it anyway.

It has been sometime since I tried to grok the SRP stuff, and last time it
was mostly to understand the more homenet related things.

  dnssd-srp> In other network environments, updates for names ending in

Our goal with front-end-naming is to provide the "rewritten internally function".

I found section 2.3.2.  Testing using standard RFC2136-compliant servers out
of place. I think it belongs in an appendix?

This dnssd-srp protocol seems like it will work wonderfully within a homenet
(or small to medium sized campus). I think that is the goal.

I don't think it will work as the protocol for a homenet to publish a public
zone to the Internet without some additional security and setup. At least,
that's my feeling at this point.
