The first point of the document is to allow us to answer that "perhaps" -
without a definition of Domain Names, we don't know.  The question includes
- are "Domain Names" just things that look like something  or are they
things that have a lot of baggage (such as means of assignment [which is
different between DNS and distributed hash tables]).

I'm not disagreeing, just underlining that until the definition is in place,
it's hard for me to be in complete agreement.

So - and not to be pointed - but in your email I reference, should I ignore
that for the sake of this document?  I mean what the message says seems to
contradict what you are quoting from Mathewson - which is fine - but this is
something unclear to me.

(I wasn't aware of Mathweson's message, I'm not subscribed to that list.)

I got 75% of the name right. ;)  Sorry about that - I don't read all the
letters on a page.
