I've used knockout.js for a few years now on multiple projects. As knockout grows, I started to dream of a library that would provide me with a two-way data binding. But not only between data object and DOM, but between data objects itself, like ko.computed does.

This seems like a nice solution, although like other commentators mentioned, the lag seems to be quite unbearable. So it might be just something towards right path and hopefully it will be maintained and updated to work more smoothly, but wont grow into full framework.
