Red Hat said, "You can create application for any platform and then consume some API hosted on OpenShift. In this way the answer is yes. If you want some MBaaS (Mobile Backend as a Service), then the answer is not by default. P.S. There is an open-source project called FeedHenry that provides this feature and is deployable on OpenShift (http://docs.feedhenry.com/v3/guides/mbaas.html), but I doubt it would work in the hackathon environment."
