Well , the good news is there are open-source baas libraries one can install on his own server, and they are fully testable. I would use a baas for a quick prototype , where the client is built first though , so there are some use cases. But again , there are a lot of script you can get that are production ready , with a RESTfull interface , ACL and user management , mongodb backed so user can upload to gridfs etc ...
