VP... given that Web2py is written in Python it might adopt an existing JavaScript-based MVC framework for client side app development. As you've pointed out, it has already adopted the JavaScript-based library JQuery. JQuery doesn't have a app framework but there's quite a few putting effort into MVC frameworks for "app" development.
Who knows... perhaps Web2py will adopt Spinejs :) All, I've gotten my spinejs app to call a Web2py controller function, decorated with @service.jsonrpc But when I return a non-number value, the client-side drops the ball. if I return an int or a float then spinejs handles the response and calls my "refresh" function enabling me to update the UI. Does this behaviour give a clue to where I'm slipping up? The best way to predict the future is to invent it (1971, Alan Kay)
