Ok, I'm assuming you only want users who have this shell to only be able
to access certian things, run only a limited set of commands?

If thats the case, then you'd be best to setup a chroot jail. That way
they can't breakout (unless they are root).

Personally, a chroot jail is the only thing I trust when I need to setup
an isolated or restricted environment. Its difficult to break out of a
chroot jail even when you are root, but it can be done. So ensure they
can't get root. :)
