The main reason was to be able to do secure dynamic DNS updates.
AFAICS there isn't support in twisted.names for that. I suppose I
should have included an example, but to do secure updates you have to
cryptographically sign the DNS packets, plus you need to control the
DNS server etc. The 3rd example at
http://www.dnspython.org/examples.html is a non-working example
(non-working because of the fake encryption key).
Sometime in the near future I'll need some DNSSEC support, but that
project is still a little half-baked so things may change.
Enhancing the README as you suggest is an excellent idea - more
projects need that sort of information.

Yes, that would be interesting to have too. I'll look into adding that as well.
