And there is the long term solution - Develop an E-mail user interface that
automatically recognizes certain types of authentication/encryption  and
automatically applys YOUR signature to outbound messages.  Include a nice
GUI interface, lots of user options for defaulting to siganture vs.
encryption on outbound, etc.  And have it available on many platforms.

Sounds like a good school project, after all, that's how Mosaic got started.

I think if you're looking for key stroke timing and rules for identifying a
human vs. system doing the sending then you'll probably have to modify the
program.  I doubt perl would be fast enough, though I don't really know.
