Which in general are a flat rate. I'll try to fill in the various issues you
raise with as real-world numbers as I can get.

Everyone who uses the system. The question is who do we want to define as
'using'. I believe the provider of information is not 'using' the system
in the strictest sense but rather making an investment of their time and
effort in somebodies elses business model and hoping that work will bring
them profit.

Assuming your 5 year plan, a 1G drive costs $100 or less. That's roughly
$20/G-yr.

Granted, but except for the sys-admin you don't need them often. In all the
years I have been in business I've needed a lawyer only a couple of times.
Say $1k/lawyer-year.

A Cyrix P200 runs about $600 for a working box (I bought one just a few
weeks ago). So that gives us about $120/cpu-year.

For reliable system administartion you're looking at 5 people (3 8-hr.
shifts plus weekend coverage of 2 12 hour shifts). A sys admin with the
skills and maturity to work in this environment is going to run you in
the neighborhood of $40-60k/yr. So this means we're looking at, on the
outside, $300k/sysadmin-yr. This is the real cost of doing business.

Not shure what the normal ratio for online versus offline storage actualy
is currently, say 10:1.

> 2) Transmission of information - Roughly proportional to MB/time -

This seems overly simplistic to me. The actual cost of the bandwidth is
reasonably fixed for a given site. Also if we throw in the other servers
this model becomes a bit more flexible. Remember, under the Eternity model
we don't know *which* server is being hit for the request. This means we
have to consider the actual end user costs in a much more complicated
fashion. It's one of the issue I'm working on myself. It does not seem clear
cut nor well researched at all.

I fail to see the profit in giving away plans for man portable nukes or to
turn commen cooking yeast into a THC producing horde when the various
groups around the world would pay so many millions (or would that be
billions) for some to get it and some to keep others from getting it. The
potential for a access auction hasn't been explored as far as I am aware.

I believe advertising would be a necessity. The question is how. Would the
payoff for doing a print ad in a magazine be worth it? Should it only
be advertised on the net?

> 3) Legal defense - This one's harder to predict :-)  

If the Eternity model works the question becomes which one and where are
they located? Whose legal defense? Which jurisdiction? Put up an offer for 1
weeks notice of any pending legal actions against the network and make it
worth the while. Say $500M. It would of course be fully anonymous and the
information would have to be testable prior to payout. Leaves two option.
First, the data is verified and the source is paid. Second, the server
goes down and the source isn't paid - thus ruining the reputation of a
server. It isn't clear to me what the total impact would be on the network
as a whole. One way to mediate this impact on a given server would be to
share the cost of the payout between the various servers. It is after all in
all the servers best interest to keep as many going unharrassed and as well
prepared and for-warned as possible.

True, but the current model doesn't allow anonymous providers as the norm
either. The users may be anonymous but the ISP isn't.

Then there is no reason to use an anonymous network, simply put the data on
their own webpage and sell it direct, cut out the middle-man a tried and
true business tactic.

> and accumulate reputation capital under those nyms.

One of the assumptions is that the source, individual server, and sink
are all anonymous to each other as well as Mallet. Now we're changing the
rules of the game in the middle of the game. Apples and oranges.

If I were actualy going to impliment something like this I wouldn't even
consider it unless I had at least $500k worth of funding for each of the
first 5 years. That start up cost, $2.5M, is what is going to kill it.
