[TriLUG] dynamic dns

[Rick DeNatale]

Dyndns.org uses HTTP and cgi for the client update interface
http://www.dyndns.org/developers/specs/

Of course they do have stable  ip addresses for their name servers.  I
haven't thought through how this would or wouldn't work in the case
where the dynamic dns server also had a dynamic address.

There also seem to be some security exposures since client validation
is done via url validation which sends the account and password info
in the clear.
