Interactive widgets on the lock screen are interactive, but very limited. When you tap a button or something in the widget, does it have to then relaunch your process in the background? That remains to be seen and that might vary depending on what kind of hardware you have. But this all depends on that speed. Is it fast enough that most people wouldn't notice and it feels like a live version of your app? Or does it feel kind of like you're putting in a order they're going to bring out later? You'll see as long as we don't have any odd throttles for these kinds of things.
