  Take a look at the event system in dojo. That may be able to do what you want.

  Thanks Derek. It could be part of the solution I think.

  Eh, why not...
  
  function fQueue()
  {
  var pos = 0;
  var queue = arguments;
  return function()
  {
  if ( pos < queue.length )
  queue[pos++]();
  }
  }
  
  function DoThingOne(whenDone)
  {
  document.getElementById("Output").innerHTML += "Thing One!<br>";
  whenDone();
  }
  
  function DoThingTwo(whenDone)
  {
  document.getElementById("Output").innerHTML += "Thing Two!<br>";
  whenDone();
  }
  
  function DoThingThree(whenDone)
  {
  document.getElementById("Output").innerHTML += "Thing Three!<br>";
  whenDone();
  }
  
  function DoThings()
  {
  var q = fQueue(
  function(){DoThingOne(q);},
  function(){DoThingTwo(q);},
  function(){DoThingThree(q);});
  q();
  }
  
  
  ...no idea if that's close to what you're looking for, but if it is and you get rich, send me a pizza.
  A *solid gold* pizza.
  With pepperoni and mushrooms.
  *Morel* mushrooms.

  There are queues in the new version of script.aculo.us
  
  see: http://www.railsdevelopment.com/2006/01/15/effe...
  
  Then use the afterFinish option for executing arbitrary code when the effect is done.

  why not use an array.
  
  var queue = new Array()
  
  //Enqueue
  queue.push(obj);
  
  //Dequeue
  obj = queue.shift()
