NeuroDocker check ReproNim/containers

This might be a bridge too far, but, as long as I'm spitballing...

Would it be useful when NeuroDocker is asked to build a container, it checks with known container repositories (ReproNim/containers, for example) to see if that same container has been built already, and if so, recommends that the user consider using that one, as opposed to creating an additional identical version of the container?

If an identical one is not known, would it be useful when NeuroDocker builds a container, to offer an option to contribute it to ReproNim/containers?
