What I'm proposing currently (and I think other proposals are having  
the same effect) implies that there is a new and separate origin every  
time a widget is newly instantiated.  The baseline policy that this  
corresponds to (and which could be relaxed later on) is the rough  
equivalent to each widget being a sandboxed iframe.

We need to figure out what the baseline policy is for access to  
persistent storage that is shared across several instances, or even  
several widgets.  The current approach simply means that there is no  
shared, persistent storage in the widget model; that's probably isn't  
what people desire.

Does this help?
