Did anybody succeed in deploying Jupyter into a multi-user environment? I know there is jupyterhub and some people deployed it for selected trustworthy users (e.g. in a university course context or a company's intranet), but AFAIK it hasn't been deployed in production to potential untrustworthy users. Current approaches seem to rely on the idea to sandbox you in a Docker environment, but mostly these are work-in-progress solutions and I am not sure how much more secure they are, beside the fact that also authentication and persistent storage issues have to be solved.

The obvious problem is that accessing Jupyter is technically similar to allowing full shell-access and you have to deal with local privilege escalation, but I wonder if there has been any progress. I evaluated to use it as a UI for domain-specific applications that give users some kind of graphical shell, but in the end I decided against it, because of security concerns.
