Apportable could be ported to run on Windows Phone, there just hasn't been any interest (or so I'm told). Much of it could also run via NaCl as a Chrome Packaged App, including the UI stuff. That's a much bigger change though, since you'd be supporting mouse events, not touch. But it's still doable.
