Performance does seem to be a problem... :-) I've always thought
of Javascript as a nice target to write a VM on, but running an
interpreter on an interpreter, even if the latter is heavily
optimized... As an educational tool it would definitely be cool,
but I'm not sure about serious apps like game scripting.
