This definitely blurs the line between calling an app native or web based, at least from a business-marketing standpoint. However, far more interesting is to see the waves of innovation that APIs have created. APIs are becoming the personality of computer systems in the sense that they allow interaction and shielding from the outside world. As long as developers know how to interact with a system's personality they can now build just about anything. Furthermore, experience is becoming the new IP so I believe that such technologies will bring more and more experience innovation by providing easier and faster paths for high-level programmers to contribute to the ecosystem.
