The solution might also be to have your own cloud instead of using a public cloud. Personal clouds seem to be growing in number over the last year. None are perfect yet, but I've used younity for a while and find that it is far and away my favorite option. The beta has expanded fast and features are added every month or two. The benefit is I have *all* my files accessible via my mobile devices, but no one else has any access to my data (it isn't stored online). And it's free to boot.
