With that not even the integrated camera-app would be able to store pictures 
into it, no?

But somehow there must be a way to exchange data between apps I think.

Also stuff like music files can't be owned by one music player without access 
for others. How would you write an app that can stream your music/video files 
via DLNA? Or just an alternative music player?

Another use case would be some application that can create pictures. For 
example some pimped camera app, or some avatar creation app. It should be 
possible to save that to the same location as the other pictures.


Probably providing some pool of "shared" media data via the Document Gallery 
could be a possibility?
