I think that resurrection of "pio template" might be one idea. It would allow us flexible repository layout and also it can rewrite PredictionIO and Spark versions in build.sbt in templates at setup time. Though this isn't a standard way (e.g. "git clone" or "sbt new"), I think it both users and developers would be happy.
