What's so scary about that?  If you allow your users to install their
own CGIs, then they've always had the ability to do this sort of thing,
wether using "cgishell" or writing a cgi that does an
"os.system('/bin/ls')" sort of call...

If you are allowing your users to install their own CGIs, they already
have these abilities.  If that scares you, you obviously need to do some
work on the security on your system.  ;-)

cgiwrap and appropriate permissions for each user directory are probably
the minimum security steps you want to take.  It depends on what you're
interested in protecting, though...
