You may have hit upon something there, Lynn.

One of the (many) reasons that PKI failed is
that businesses simply don't outsource trust.

If the use of TCPA is such that the business
must trust in its workings, then it can fairly
easily be predicted that it won't happen.  For
business, at least (that still leaves retail
and software sales based on IP considerations).

It is curious that in the IT trust business,
there seems to be a continuing supply of
charlatan ventures.  Even as news of PKI
slinking out of town reaches us, people are
lining up to buy tickets for the quantum
crypotagraphy miracle cure show and bottles
of the new wonder TCPA elixir.
