From what I read in the paper, it sounds like you _don't_ get paid for providing the data. You get paid for proving you have it when mining a block. Distributing your storage across multiples nodes would simply make it easier to "mine", but wouldn't get coins passively. That is, if I'm understanding the protocol correctly.

You're right that nodes get paid for proving. Though you do also get paid for providing pieces in Get transactions.

On outsourceability, Filecoin today makes no effort against it. But see Permacoin for a great (and compatible) solution.
