[K12OSN] root script query

[Alan A Hodson]

Gretings

To help control senior moments and distracted local users, how 
difficult would it be to develop a script that logs root out of the 
system after say three hours of inactivity? I imagine many processes 
run as root, but if keyboard activity can be isolated, maybe the 
script can monitor that and just log out, no?

Thanks for any/all help
