Any projects to provide Javascript-style client-side browser access via Python?

Python isn't a good choice as a browser language because it doesn't
have enough security.  Hostile scripts can take over the interpreter
too easily.  

There was a Python-based browser effort called Grail which I don't
think got very far.

Personally I think there are very few good uses for complex client
side browser scripts.  Most sites that use Javascript don't really
need to.
