Maybe they should just recognize the fact that the web has won and nobody cares about X any more, and implement a window system that runs in the web browser, and run the web browser in full screen direct access mode as the only top level application. I mean, now that we have HTML and WebGL and Canvas, who needs X11's neanderthal rendering model?

I'm kinda surprised that nobody's written an X server in JavaScript yet (not that it's what I'm proposing above, just that people love to do crazy useless things like that).
