Speaking about transition of graphical applications from one device to another, I think this is a rather difficult problem in itself. The only project I'm aware of, which tries to enable that in a seamless way, is the Arcan display server. I remember a short clip from the development blog [1], where a window with a running retro game is pulled to the edge of the screen and appears immediately on another device nearby [2]. Unfortunately Arcan is pretty niche and I doubt that will change in the foreseeable future. Using voice commands to control, where your applications is running, would then be relatively easy. Swiping in that direction, while pretty cool, is much harder, as you would need to locate both involved devices.
