What's missing from Safari in order to just implement this directly in a browser window? AFAIK, Apple has never stepped over the line of blocking specific websites. As soon as it's possible to reliably remote stream an interface through the browser then the App Store and pretty much any native app at all can become totally irrelevant, offline mode aside. If a device is reduced to a touch interface, video stream decoder, and a bunch of radios... your upgrade cycle becomes essentially driven by the carrier baseband upgrade cycle, which is quite slow. Who care how fast the phone CPU runs Javascript, when the Javascript is running in the cloud? It's like thin terminals all over again.
