Actually these are the exact same problems that could be solved much 
better with some kind of per activity DS (not the Android one, which 
would be a little bit overkill). I mean that even making or not making 
deltas is dependent on the object the activity stores and the deltifier 
is also activity object dependent. Also the single file or multi files 
thing is activity dependent and so on. So you can implement every 
possible feature in a global glorified DS but I personally do not think 
that you will reach a really usable general DS ever.
