I don't plan to compete with those huge services and their catalogues.
Instead, I'm building a platform as a service. My ideal customers will be the software publishers that want to run their own streaming cloud. There's a lot of demand for enterprise solutions that allow you to demo things online. With a regular unlimited demo version, you have the risk of people trying to crack it. If the demo is a streaming service, then you can use everything, but copy nothing.
In essence, a high performance streaming solution is the perfect copy protection for pricey enterprise apps.
