Yes.  A Bayes analyzer would pick up on patterns that a person might
miss.  We have a Bayes-sharing mechanism for CanIt customers called
RPTN, and I am completely amazed at (1) the oddball things it picks up
that I would never have thought about, and (2) how accurate it is.

(Basically, RPTN aggregates "votes" from all of our CanIt customers
and builds a Bayes database from them.  We have about 90,000 messages and
900,000 tokens in our current database.)
