Launch Applications with Dev-provided Place-able Objects
As a game developer, I would like to be able to submit a 3D model with my app that owners of my game can place in their homes, which also let them launch my game with their friends. For instance, the object could be a chess board, or a snow globe with a representation of my game world, or a figurine.
Then players could walk up to the object and be prompted to play my game with coordinated launch/deep linking/etc.

A portal set inside home would be great too. The portal don't has to be a literal elliptical wobbly rift in a wall, but could be some item. It would become really great, if we could look into living scene of the application/game through the portal. Or watch something happening inside an intricate object.
Imagine a chess board, where you would have to make a certain move, which triggers a reshaping of Home into the game world.
Or you pick up a bow and a flying monster spawns at the open side of your Home, once you shoot it, Home breaks apart under which the game world appears.
Pick up a shotgun and an elevator is morphing from the wall. Once the doors open an enemy from SuperHot enters your Home.
That would be the next level of immersion to me.
