The project is still new but I have written a complete example app and have been building a far more complex app since.

Listsurf: https://github.com/j2labs/listsurf

The more complex app implements a full social network on top of Brubeck. I think it will be called Rubik, but I'm not sure yet.

It'll pop up on my github page sooner or later though: https://github.com/j2labs
