Actually the whole DNS caching and forwarding scheme is simply analagous to
a nice and easy heuristic greedy algorithm. It's not perfect......but it's
about the best you can do without being rediculous.

The last time I had a reason keep a copy of the root file
locally was back around 1999 and I think .com alone weighed
in at over 3 gigs (I think that was uncompressed, but I've
been hit in the head a lot in the last six years so I don't
quite remember). I know you weren't serious, but at it's
uncompressed size in 1999 it would be bandwidth cost
efficient to send the root file to someone only if they were
to perform approximately 6.3 million queries per version of
root file (which would of course become outdated during
transfer). Now lets say it's only a one time transfer and
after that only updates are sent. Well forgetting the
bandwidth generated by the updates, if a person performed 200
queries a night it would take them about
86 years to reach the 6.3 million needed to make the initial
transfer cost effective.
I'm sorry, one should never answer angry and I'm well...okay
I just think it's stupid to do away with the root and I think
dns delegation has exquisite scalability and near absolute
empowerment to the people. Any possibility that the Internet
might not be able to support DNS resolver traffic because of
a root server bottleneck is beyond my concept of reality.
If it truly is a bottleneck then maybe we need to seek the
advise of some adult webmasters and ask them how they manage
to serve multiple terabytes of porn a day without breaking a
sweat or bringing down their ISP. Considering that when two
technical people have a discussion you end up with 3 opinions
that neither one agrees with I feel somewhat better not
"letting everyone play" in the root. In fact I'm all for
fairness but I'm not about to agree to tearing down a genius
system just so foreign nationalists can have their ego
satisfied by sticking their finger in the pot (Jefsey the
foreign nationalist comment IS NOT directed at you at all -
it's directed at the politicians and delegates who live life
like it's a game of push and pushback).
My apologies for the rant, I'm sure I'll regret it when
someone who knows more than me replies explaining why I'm wrong.
