I disagree, I think the cloud stuff actually makes this even harder (at least today). The distinction between what's in the cloud and what is local is extremely hard to make, even for those of us that live and breathe this stuff. Oh sure, you can define it, but as a practical matter, if I hand you my phone, can you tell what's on the cloud? Is it left to the vagaries of what the OS has happened to cache locally? If you open my Dropbox app on my phone, how do you know what files are local and what files aren't? What if you see a filename like "drug_customer_list" in the directory listing? Can you go get it now that you have probable cause? It's murky and messy. We can pretend that it's simple, but it's not and we will need to work all of this out.
