I could be totally wrong and maybe this approach has already been considered but what about finding a way to put the content on a blockchain with multi-signature smart contracts? Granted the information would live on the blockchain but access is only granted through a mutual agreement and everyone else would be locked out. I know blockchains are a buzzword lately but I do see a lot of potential in their application. I'm not sure if what you're proposing is more for a full-fledged streaming service like Netflix or simply giving someone from the press access from home for a preview. I think the blockchain approach might work better for a preview rather than a full streaming service.
