Think of a blockchain a OSS Visa like payment network where you and anyone else can build their own apps, be it something as trivial as a multi-sig or a token exchange, for instance. From this angle, I think it makes more sense to investigate Ethereum and smart contracts in general.
Regarding accessing external data, that is done via oracles and is a well researched topic with some notable implementations (Oraclize, Town Crier, etc), but I'd venture that the most common way to integrate a web3 with web2 is and will be at a middleware level, not directly on a smart contract.
