I'm not sure I get it.. There are already several two way DOM <-> data binding frameworks, e.g. Angular, knockout, ember. What does this do differently? It reads more as a presentation layer thing, but presumably you could do this with one of the above frameworks right now...

Perhaps a walk though of how to build a complete brick would be useful in demonstrating to differences and uses. Does anyone know of one - I couldn't find such a thing in the docs?
