Maybe I've missed part of the specifications - are you telling me that I 
can package up an HTML,CSS,JS based application as per the widgets 
specification, include a WARP, Digital Signature, set the view-mode to 
windowed and that this will run as is, in the main browser context of 
the main browser vendors (Firefox, Safari, Opera, Chrome, IE etc)?
