I don't know about VeryNice, but here is a script I wrote to kill
user processes. Go here
http://www.rossberry.com/writings/sysadmin.html
and scroll down toward the bottom til you find 'kill.pl'. Season to
taste.
You could add logic to check for certain types of processes against
the list of who is logged in, then kill those, or send email to
someone to check. Sort of a grim reaper cron job.
