No. I was comparing the requirements against my ability to imagine messy details. I suppose Docker jumped out as a different level of abstraction relative to the general problems of scientific reproducibility; the diversity of scientific investigations; and the existing social and physical infrastructure of scientific laboratories.

I suppose the sort of messy detail I might imagine is how does a Matlab license work in terms of multiple containers. And the details are messy because of legal and institutional constraints in the markets I suspect are looking for this solution.
