Of course, this whole process will take a week because someone will
misunderstand Geoff or how netnews works, and start posting about
how such a system actually *would* work.  This person will eventually
be proven wrong also.
 
All the while someone will write a script that checks various
parts of a post message to be a little more sure that the post
wasn't forged.
 
Of course, that just means that forgers will only need to be a bit
more careful when crafting their forgeries for them to work.  After
a few iteration of attempts, they'll have perfected their technique.

Summary: Oh nothing important.  I just have this Perl script that I use to generate this stream of posts whenever someone posts the silly suggestion that netnews could be made secure.
