I just pulled down the Cool security stuff for later perusal.  I suppose
at
this point I'm mostly directionless with regards to security on user-
programming and hope to spark something that pushes me one way or
another.

Does that imply that a user can come along, and, say, take a small,
no-frills
bag and turn it into a big bag that hides its magical contents from the
rest
of the world?  That is, the user has mostly free reign to tack on code
that enhances objects in the world (depending on what the security of
that bag allowed)?

You'd earlier posted a bit about how a user could code up a 50000hp
damage
wet noodle, but when using it nothing of the sort would happen.  I was
wondering how does the noodle make the determination that that sort of
thing shouldn't be done in this context?
