Considering the number of garbled articles and the constant discussion
about what site using what form of batching clobbered what line,
shouldn't we consider adding a header line containing a checksum?

The checksum would have to include the unchanging header lines and the
body of the article.  The path, forwarding version, xref, etc. headers
would have to be excluded from the checksum.  Or, the checksum could be
recalculated as the headers are modified.

With a checksum and the sendbad control message we might have some
chance of cleaning up this problem.  The log entry left by the sendbad
control message would also be an indication to the SA that there is
something wrong in the feed.

The only hard part of this comming up with a checksum that is portable
across the wide varity of machines on the net.

Comments?
