I'm not sure what other constraints we want to place on file access. Is there a canonical list of permitted/disallowed locations that we should be checking?

That's a great question. I do not know what we should disallow.

We cannot enforce a policy which we do not have. Ship it! (Unless you want to tweak the nits, first....)
