Right, I guess I should have been more specific.. I am going to have a simple password protected page. I want to be able to provide the password to certain people and allow them to upload files through the comment form (ie by just adding another field) without actually having to visit the admin interface. The files would then show up as a link at the bottom/top/side/somewhere of the comment.
I imagine it wouldn’t be too awfully difficult to do something like that, but I thought if someone else had already done it that it would save me the trouble of much trial and error.
