Isn't what google is doing with dart ? I thought they had plan to embed a dart vm inside chrome. As for css i still haven't found a layout framework that would let you design responsive UIs easily. It seems to me that coding in fix positionning is easy in any system and coding for flexible layout is hard no matter what you're using (eg : which of iOS autolayout or CSS 3 is the best ? Hard question)
