Nope, we don't use it but it is a very cool project. We have SDKs for Android, Objective-C, Swift, Java and Node.js so far. That's why we couldn't us it anyways. We don't want to compete with open source projects like this. Our goal is to offer easy integrations for all platforms and all major use cases (not only cloud storage). Btw, to support open source, we made our solution free for non commercial projects.
