To me, this looks like a really cool tech demo without a clear purpose. I can think of several possibilities: For instance, teachers using this as a way to distribute examples for people to play with, as an improvement over paper hand-outs. Or as a tool for remote tutoring, as in the collaborative drawing example. Or as a tool to organize study notes. But I think it would help if you choose a single use case and focused. If this is a tool for remote tutoring, try to integrate it with other similar services. For example, a built-in code editor. (There was a really cool online tool I saw a while ago that let you step through python code line by line, showing the currently defined variables and values at each step, with arrows and such pointing to objects on the heap...). Basically: the technology looks really cool, but it's hard to say anything else. I'm not sure who this is aimed at.
