Sproutcore

Sproutcore may be just the framework I've been waiting for. It was always pretty clear that the application should be written in JavaScript and the server should serve data. With recent progress with REST, JSON and now Sproutcore, it looks like we are there. It might take the Sproutcore community a year or so to push get some "maturity" on this. But given the activity on the mailing list and wiki, it may take considerably less. And remember, this is not something brand new; it has take a couple of years to get to this point. Have a look yourself.
