The thing is: inter-widget communication is off the table for v1. I  
believe that we do need to say something about multiple instances,  
that is along the lines of: a widget available inside a given UA  
always has the same opaque globally unique identifier, and needs to  
retain the same across invocations so that origin-based decisions  
work. If multiple instances of the same widget are launched  
simultaneously, then they all have the same opaque globally unique  
identifier. It is up to them to differentiate one from another, if  
needed.

And I think that's all we need to say.
