Before discussing any particular use cases it's better to start from the basics and decide if you are interested to incorporate Blockchain 2 capability into your software at all.

Not a lot changed since we discussed this topic 2 months ago. I suggested you at the time first please go through on Ethereum's Gavin Wood's yellow paper at http://gavwood.com/paper.pdf (that's more a research paper in my opinion than a generic software document) to get an idea what I am talking about when I am referring to contracts and get an idea what should be done terms of functionalities and development effort to support smart/decentralized contract technology. As you can see from the yellow paper and from their source code, which is freely available for your reference Ethereum is not doing any extra special, your team is perfectly capable to carry out such software development, we are talking about a fairly trivial software engineering task to implement smart/decentralized contract handling. When technology leaders like the Linked in founder Reid Hoffman thinks that the smart contract technology will radically change how we do business from recruiting to legal services, from currency exchange to tangible/intangible asset transactions, then probably it is worth start listening.

Anyway, it's just my opinion that worth to focus on a novel technology like smart/decentralized contracts. Once you start to work on it, such technology development will put you on the news for the very good reasons - unlike the decentralized cloud storage which will associate you with a very shady use case.

It's up to you, to be remain James' pet toy and wait what task he assigns to you (like this decentralized cloud nonsense that His Highness generously assigned to you) or establish your coin as a technology leader by implementing on your own a novel idea in your blockchain.

Before that, I also suggest to start building your marketing strategy around Barabbas' Bank vs. honest digital currency theme, that was an excellent idea in my opinion.
