I don't recall Angular 1.x having a shared local/remote persistent storage API with built-in local and remote drivers and a storage driver SPI.

There's considera le feature differences in the simple templating functionality of this vs. AngularJS 1.x, as well (Angular seems a bit more powerful overall, but this seems to make some of the common things simpler), but I think it's the storage integration which is more of a fundamental difference.

A little bit, yes, but I feel that they are at least on to something here.

Look like Angular 1 to me as well.

Anyway the idea is nice!
