I'm not saying it is a "bad" or "wrong" thing.  But it has to be
pointed out that the possibility for Trojan Horses here is
mind-boggling.  One of the students here had FTP'd a shar file
from a BBS that he thought contained pornographic images.  When
he ran it, it archived and encrypted his directory and told him
where you could send $50 to get the password to unencrypt his files.
Serves him right, I said to myself (not because I'm a moralist
crusading against pornography -- just because you have to be
pretty bleeding daft to run an untrusted shar file in your home
directory).
So, does your patch try to use a restricted shell?  If so, what
commands do you limit the agent to?  Do you chroot to a temporary
directory?
