Small addition from my side. I've been playing recently with a very 
naive reuse of BasicExternal infrastructure which is supporting external 
objects in JS backend. Looks nice so far and I'm able to hard code some 
RPython-accessible objects (in a very ad hoc manner, mind you). I don't 
know Java that well, but I would be happy to help with this issue.
