Thanks. It's quite interesting.
Actually, I am not the "porteur de projet" (I am not a stakeholder of that MoodleBox Wiktionary embedding project).
I have also recently seen on the French forum that some universities do use a MoodleBox to give courses to "empeached" students : prisoners inside a prison, without an online connection.
(I am not taking parts to these two projects : I am just disseminating the info from the French-language Moodle forum here.)
