Yup. Many moons ago, at a previous employer, you had to log into a special
machine to get Internet access. Said machine logged you into an environment
where:

- Your umask was 177
- You had no access to the umask feature (nuked from the shell builtins,
  etc.)
- You had an _extremely_ limited command set available, none of which can
  create executeable files.

That's all you had to do to keep the user from putting his/her own code on
the box.
