Another use case I’d like to point out: the folks behind NASA’s @Open-MBEE/ve expressed some interest (including prototypes) of using Jupyter-kernel-created plots inside their View Editor (not so much into branding), which is basically like multi-user Word powered by a (ridiculously) deep underlying model: e.g. The ancipated transit time from [orbit x] to [orbit y] is [z hours]. These numbers would continuously update as a space mission is planned by expert users of engineering-grade tools.
One of their desires is if you want to play a what-if, you could actually click on a plot and get dropped into an interactive environment, and be able to comment on stuff.
The current editor is built on angular, but telling a compelling story on top of Lab seems like an important play to be able to make.
It’s certainly worth dropping them a line: they’re just down the road in Pasadena
