Incidentally, I too was intrigued by Chromecast [1] and the similar Miracast because these are technologies that dance awfully close to where user interface push and pull should go. But they are constrained by narrow thinking, leaving them frustratingly limited and merely bite-size demonstrations of what multi-device life should look like. Both only push views, and are only read-only without a whole lot of context adaptation.
