Well, I dunno. Part of me is trying to get to the bottom of why the PyPy 
guys hate RestrictedPython so much. It seems a robust way of providing a 
secured (as opposed to sandboxed) pthon environment and while it 
requires work when the AST changes, I've yet to see someone suggest a 
suitable alternative, as this discussion has kindof showed ;-)

I'm not sure where you could generically plug in the un-proxying code...
