Here's one you could try:
Code:
Restrict number of logins allowed for a user

To restrict multiple logins, place the following lines in the users .profile 

# Limit number of logins allowed
Times_allowed=2
Time_in=`who | grep $LOGNAME | wc -l`
if [ $Time_in -gt "$Times_allowed" ]
then
  echo "$LOGNAME is already logged in $Times_allowed times!"
  exit
  exec /bin/login
fi

Then chmod 444 and chown root .profile
