You have a people problem. Start by dealing with it in
peoplespace.

1. Write a policy on how to administer the machine. Publicize
it. Get people to agree with it as a condition for super-user
access.

2. Nobody should log in as root. They aren't accountable that
way. Require sudo; prevent root from logging it except at the
console.

3. Rename halt, reboot and shutdown. Write wrappers that issue
automatic wall messages, wait for 5 minutes, check the existence 
of a file (/etc/noshutdown?) and then continue or not.
