This is kind of how sandboxed apps on the Mac work - they can only see files or directories that the user has manually opened in the app though one of the OS facilities (double-clicking a file, drag & drop, or the OS-provided file open dialog) It would have been nice if you could just force non-sandboxed apps (basically anything from outside the Mac App Store) to be sandboxed.
