Sorry, yeah, I deleted that after re-reading your post because I realized I needed to think about this more, and what I was really about to suggest was something maybe more like site access, I suppose, with all the file downloads in one area of the site or something. It wasn't a great idea either, so I just deleted it all, and thought I'd think about it and come back to this later. Sorry I'm not more help, see if thinking about site access gets you anywhere, but probably also not.
