Right. I'm unopposed to allowing programmatic enumeration and access  
to such files without user interaction as long as the user  
interaction to deem files public in this way is obvious and trusted  
(e.g. from the journal). Eben?

You don't want an activity being able to deem a user document world- 
readable; you want the user to do it herself. What about files an  
activity ships? There's an argument to be made that the activity  
ought to be able to deem some of them world-readable in the manifest.  
This doesn't make me _happy_, but I could potentially be convinced  
it's a good idea. So far, no one has put forward a really compelling  
argument.
