If you use

     SUElement new

the element won't be able to render, as it doesn't know the context.
Therefor you should use the factory methods

     html element ...


     html scriptaculous element
     (the new way of doing it)

what basically does the same but assigns the curent context to the
element, so that it can do fancy stuff like rendering and registering

Why don't you use the periodical updater then? Is there a difference
between pulling every 5 seconds (AJAX, Scriptaculous, easy) and
pushing every 5 seconds (Comet, relatively complicated and resource
