Scott and Microsoft team says they are going to not continue (by now) with the upshot.js development.

I´m going to stop studying this library.

There is a pretty good discussion on StackOverflow of the Upshot situation and alternatives. The net of it is that Upshot has been abandoned and, fortunately, there are some good choices of libraries out there, including BreezeJS, Ember, and JayData
