> Can you elaborate where CallWith=DynamicFrame is going to be used?

It's for places that need to pass a Frame* to WebCore and were they need the
frame to come from the dynamic scope (instead of the lexical scope). 
LexicalFrame should be more common, but the first example I happened to see was
the DynamicFrame.

No.  ScriptExecutionContext is a Document-lifetime object (actually, it often
is the document).  Frame is a Frame-lifetime object.  These objects hare highly
not interchangeable.  :)
