Done.

+  // Takes ownership of |proxy|.
+  VirtualKeyboardController(VirtualKeyboardControllerProxy* proxy);
+  virtual ~VirtualKeyboardController();
+
+  // Returns the container for the keyboard, which is owned by the
+  // VirtualKeyboardController.
+  aura::Window* Init();

Perhaps Init() and GetContainerWindow() should be separate.

[bryeung, 2013/04/02 15:56:53]

Done.

+  // FIXME(bryeung): there's a crash on shutdown...maybe I don't get to own

By default, an aura window is owned by the parent. Perhaps in this case, you
want to set_owned_by_parent(false)

[bryeung, 2013/04/02 15:56:53]

Done.
