How to prevent VI from getting a shell?

[Chris Rende]

If I want to give someone access to VI and yet deny them access to a shell,
how do I prevent the user from using VI's "<ESC>:!" command?

I have an application program which launches VI. I don't want the user to
be able to get to a shell from VI. (I also don't want the user to be able
to launch other commands from VI. I.e., No :!pwd, or !!sort, etc...).
