In Firefox, you can do stuff like this:

var w = window.open("handler.html");
w.addEventListener("DOMContentLoaded", function(e) {
     var targetWin = e.target.defaultView.
     targetWin.postMessage("Hello", "domain");
}, false);

But, I think that only works in Firefox. In Opera at least, I'm sure it  
doesn't work.
