I'm not sure if I understand exactly what you're trying to do, but I  
have implemented a multi-window Athena app by sharing the LiveElement  
among the windows.

The drawback is that if the window holding your rendered LiveElement  
goes away, your child windows will lose their connection to the server.

In my case, I just have one LiveElement that handles all the  
communication between client and server. This is part of the main  
window, which also has a function like this:

     function getConnector(){
         return Nevow.Athena.Widget.get($('athenaid:1-client- 
connector'));
     }

At this point I can callRemote() on the returned object instance.

This works for me because of the simplicity of my application; with  
only the one LiveElement it seems that the Athena ID never changes, so  
this has been working really well for popping up editors and complex  
dialogs and so forth.

Also, I don't think I've ever tested this very thoroughly on IE, so  
YMMV.
