Let me explain a bit better why I’m asking.

Yishay and I are working on a URLLoader class which will behave similar to the 
Flash URLLoader class. Is there any reason not to make both the Flash and JS 
version extend EventDispatcher? From what I can see, the flex EventDispatcher 
on the JS side extends goog.events.EventTarget. Is there a concern with using 
that instead of HTMLElementWrapper (which as I understand it uses native DOM 
elements to dispatch events)?
