Add this to the global profile (/etc/profile or whatever) otherwise the user will just login, vi $HOME/.profile, and remove it....

Code:
MAXLOGINS=5   # or whatever
WHOAMI=`whoami`
CURRENTLOGINS=`who | grep -c "${WHOAMI}"`
if [ "${CURRENTLOGINS}" -eq "${MAXLOGINS}" ]; then
  exit 1
fi
# no need for else.... rest of profile goes here

screen-ir

SCREEN-IR(1)							   Axel Beckert 						      SCREEN-IR(1)

NAME

       screen-ir -- Interactively Reattach to GNU Screen sessions

SYNOPSIS

       screen-ir [additional screen options ...]

DESCRIPTION

       screen-ir uses iSelect(1) to interactively reattach to running screen sessions.

       Use the screen option -d or -D if you want to reattach to attached screen sessions.

       Use the screen option -x if you want to attach to screen sessions without detaching them.

FILES

       screen-ir sources ~/.screen-irrc if it exists. It recognizes two variables:

       The contents of SCREEN_OPTIONS is given to screen(1) as command-line options. Default is -r. Use e.g. -rd if you always want to reattach to
       already attached screen sessions.

       The contents of ISELECT_OPTIONS is given to iselect(1) as command-line options. Default is empty. Use e.g. -f if you always want to see the
       interactive selection, even if there's only one screen session running, i.e. you have no choice.
