What do you think of a new standard for delivering instant web apps that is 1% of the complexity of browsers? Something, maybe a chat-like interface with buttons and input fields, that allows you to interact with a web server in a dynamic and useful way but it's at the same time very simple and fast. Ideally then for all more involved software experiences native software would have to be shipped.
