There used to be an Anti-idle script here on this site in the.tcl scripts page. I do not know if it has an option for voice/op list.
Just checked and yes there is such a script that has options for ops and voiced. Look on the scripts page for "blackidle-1.06.tcl" Don't know if it works or not, but you should give it a shot.
