This may be worth it for the transition from lab project to app prototype but I would be seriously wary of deploying anything significant on a proprietary cloud in a proprietary language. Does anyone remember when Google App Engine hiked their prices? A lot of people had to switch off the platform because the traffic patterns of their apps did not work with the new pricing. That could very easily happen here and you'd have to port to a different language, not just a different runtime.

In my senior year of college we built some computer vision stuff in matlab (pretty similar) that we ported to C++ to put in an iOS app. It would have been cool to get a quick prototype by exposing some of the functions as web services but there's no way I would release on the app store with that setup.
