Well, I don't know of people *working* on them, but I'm sure they *are*
possible. I've explained how I think they can be done in a previous
posting, so I won't bother saying again this time.

Wrong (from what I can tell).

You can really do easy damage if someone has re-enabled the file operators
by typing 'dwrite Mail _NXBypassNSC YES' in a terminal window, but this
has nothing to do with "Public Window Server".

"Public Window Server" controls who can access the window server. Since
the EPS mail-bomb is run by mail with your user-id, this has 'security
feature' has preventative effect on mail-bombs.
