You might be able to think of and disallow the most
obvious security holes, but how confident are you that
you will think of the bad code that your users will
Are you concerned about malicious users, or just
I suspect your best bet might be to write a
mini-language using Python, and get your users to use
that. You will take a small performance hit, but
security will be very much improved.
