Timing out a filepro session in bash

So, I've discovered that TMOUT is not my friend at all (it only has to do with those 
times when the shell is idle waiting for interactive keyboard input; once you launch 
a program it has no effect).  As long as I'd posted this (totally OT as it turns out) 
question on the list, let me share the script I've created for myself.  It is written 
for use with remote ssh sessions and will select by IP address, but could easily be 
changed to username instead.

Tested on White Box 3.0 (a downstream repackaging of RHEL 3.0).  Other flavors/OS's 
may need adjustment.

#!/bin/bash
# idleout

# Kill sessions by address which are idle 1-60 minutes
#
# Should be run as a cron job:
#
#       * * * * * /usr/local/bin/idleout 10.0.0.172 3
#
# This will terminate any/all sessions originating from 10.0.0.172
# which have been idle three minutes or longer

IP=$1
TIMEOUT=$2
LOG=/var/log/idleout.log

dohim() {
         echo -e "    Ready to kill pid's on $TTY" >>$LOG

         PIDS=""
         ps -t $TTY | while read ps_line
         do
             set $ps_line
             [ $1 = PID ] || {
                 echo -e "\tKilling $1" >>$LOG

                 ###### Comment this out for testing ######
                 kill -9 $1
                 ###### Comment this out for testing ######
             }
	done
}

echo "---------- `date` ---------------" >>$LOG

w | grep $IP | while read w_line
do
     set $w_line
     USER=$1
     TTY=$2
     WIP=$3
     IDLE=$5

     echo "IP ${WIP}: User $USER on tty $TTY idle $IDLE " >>$LOG

     case $IDLE in

       *[0-9]s) # Idle time is in seconds, forget this guy
                continue ;;

            *m) # Idle time is in hours, do him
                dohim ;;

         *days) #Idle time is in days, do him
                dohim ;;

             *) # Idle time is in mm:ss format
                Minutes=`echo $IDLE | cut -d: -f1`
                [ $Minutes -ge $TIMEOUT ] && dohim
                ;;
     esac
