I actually ran into this while doing some research. One thing that worries me about using this framework is how much freedom would I get? I really need custom widgets, such as chat, videos, images and many other types. Do you think this will handle the large amount of custom code on top of it?
I don't see anything that would stop you from implementing it in that framework. It does have a some users, and if shopify uses it then it must be fairly stable and useful.
You might not even need to make one on your own, or at worst you can re-use a lot of it for your use case. It uses batman.js i think.
