Do you mean like implementing the DOM in Python, and providing DOM 
objects to Javascript?  Or actually watching the Javascript execute at 
some level?  Providing Python objects seems like a kind of bare minimum 
usefulness, and must already be possible at some level in current 
Javascript implementations.  Actually watching the program runs seems 
harder, and depends on the particulars of the Javascript interpreter 
that you are embedding.  Though I'd guess that already exists to some 
degree as well, because for instance in current interpreters you can 
limit the amount of time the Javascript is given to execute.
