It seems to me that sync is the last mile for a great write once deploy everywhere (Mobile + Web apps) framework.

What I really want is a meta framework that runs rails/django for backend + angular/ember for frontend + cordova/phonegap for mobile + responsive display with HTML/JS/CSS + something for syncing to allow offline mobile. Ideally this would be loosely coupled so you could choose your components (i.e. write a native mobile app if you want, or do the backend with Go, etc.)

The two pieces still missing are the sync component and the glue that keeps you from having to define the same thing multiple times. Unless there's something open source I'm unaware of.
