This is an excellent point of rhetoric. Perhaps we should teach mail
and news forgery as a technique to the defense of privacy? 1/2 :-)

I have convinced myself that some form of secret sharing will be
necessary for a distributed system that is robust against single point
failure. You don't want single point manipulability, either, if you
can get it.
There are two basic ways to proceed: hard nodes, difficult to take
down, or soft nodes, easy to reconfigure around. Both approaches
should be looked at.
Hard nodes are more difficult politically; soft nodes are more
A soft node necessity: a directory lookup service, distributed,
sharing data. Merely specifying the first point of contact and
alternate paths doesn't cut it. You don't want to have to retry a
bounced message so many times.
Who here knows enough about sendmail to consider the eventual
feasibility of integrating pseudonym lookup into mail transfer?
