At the end of the workshop somebody asked me how to install JupyterHub for his classroom environment (at least that's how I replied/interpreted the question) but I was unable to help.
Anyone interested may like to look at this workshop which was held last Friday by the JupyterHub team. Hope that helps.

Actually, that question inspired me as I'd really like to go farther with educational/tutorial environments using Jupyter. If there's interest I'd really like to propose something like the above workshop for EuroPython next year.
