In answering you last question (and editing it for it wasn't GEMS but OPAL), it is here:
http://cointelegraph.com/news/113014/opalcoin-joins-the-supernet-core-partners-with-storjAnd, specifically, these paragraphs: Decentralized storage offers many times the security of centralized cloud storage companies such as Dropbox and Google Drive. This is particularly relevant to companies and individuals that deal with sensitive information.
Not only would the information be distributed among hundreds, if not thousands, of Storj contributors, but it could also be encrypted with a multisig address instead of a single-signature one, further decentralizing and securing access to those files from the client side.
What I said earlier still applies. As I understand it, OPAL is planning to use the MetaDisk API to support additional functionality in their own project. If they use the API to upload a lot of encrypted data chunks to the Storj network it's certainly possible that many farmers could end up receiving those chunks. But inside the Storj network it's the same deal.
