well, you could do it for all the users, something like: 
    who | while read WHO WHERE WHEN ; do 
      case $WHERE in 
          su -c "DISPLAY=$WHERE xscreensaver-command -lock" $WHO

Replace "xscreensaver-command -lock " with some xlock command, and make
it loop while you want to have their attention in some way.
