This technology is very clever and bound to be extremely important.
But does anyone else think that the price is a little high? I mean
the marginal cost can't be more than a few seconds of CPU time for
each time stamp...
This price tag will temporarily put the time stamp technology out of
ubiquitous use, where every piece of e-mail, homework paper, Usenet
post, etc., is automaticly time stamped in a cryptographically secure
way so that authorship can be asserted and proved. I think the
need for proof of authorship is going to become increasingly important
in an increasingly online world, where copying is so effortless, and
reputations are based on digital identities.
