Using code from @Anu's suggestion - my fiddle, you can simply add a poll

$(document).ready(function() {
  $(".dismiss").click(function(){$("#notification").fadeOut("slow");});

  setInterval(function() {

      if (message) $("#notification").fadeIn("slow").html(message);

   ,10000);
})

the message could include a timestamp to see if you had notified earlier instead of sending an empty message if no notificati9on is needed

Alternatives: Long poll or Comet
