I have the need to syslog every command issued by a given set of users on a given set of systems for security auditing purposes. I want to provide a wrapper around the shell of their choice, and simply syslog the command before execution. The problem is that I need to transparently wrap any given shell, while still giving them any readline-esqe command editing abilities.

This program will be their login shell, to prevent escape to a non-logging shell. Are there any modules that can assist me, or is there a standard way of doing such a thing?
