If you are using System V, you could try making all lines dailup & setting
the dialup password, or, alternativly, if you are seriously paranoid,
using the sublogin system.  The sublogin system (or whatever it is called)
works by putting a * in the shell field of the passwd file for the user,
then login does a chroot to the directory field, and then runs login again.
See login(1), and maybe other manuals as well.
