Thanks Viral, Let me know if I can be of any help testing a newer version of Jupyter (if installing a newer version is feasible and not too time consuming). Or I could point my iPad to a test version, whatever is easiest.
As far as testing dedicated compute engines is concerned I am also very interested, not just for Stan, but more so for some other applications. Inspired by another utopia thread on this list, the dream here is to make this awesome tripleJ-some (Julia, Jupyter and Juliabox) a solid foundation for cloud-based EDx courses.
