  My personal opinion is that they are all substantially similar in
concept:  EHLO/HELO, MAIL FROM, reverse IP lookups in DNS.  The
implementations differ, but mostly in syntax of queries & policy
statements in DNS.

  I'm in the process of updating the discussion paper, and hope to
have something out later this week.

  I'll take a look at writing an overview document, but I'm not sure I
can do an acceptable job.  I can *edit* one, if the individual authors
are willing to provide content.

  What I propose is this: the individual authors should write text
comparing their solution to the others.  The text doesn't have to be
large, but it should point out the limitations & benefits of the
different proposals.  It should also discuss which solutions are
orthogonal.  The following web page can be used as a basis, for issues
which do *not* need to be addressed again:

  The issues which should be addressed are *technical* ones, such as
syntax of queries, syntax of policy statements in DNS, what kind of
policy statements go into DNS, etc.

  These summaries should be sent to me *off-list*.  I will take care
of editing them together, and posting an overview document, for
general review.  We can then decide where to go from there.

  I'd like to have the comparison text by next Monday.  I'll post an
update later that week.
