No offense but that's a really stupid idea. As soon as you share your files with some of your "buddies" or your "family" you can consider them public domain. It's the typical end-user nonsense request anyway. Every tool has a very precise purpose and if you turn it into a can-do-everything it becomes digusting crap before you counted to 3.

There is a bazillion of possibilities to share "private" files using password protection. Why the hell wouldn't you use one of those? Right, because your screw driver should be able to, shouldn't it?
