You want offline support with it? Oops, it's included!
Today is a good day for web applications. dojo.storage is announced to the world. I have been dreaming about occasionally disconnected applications in the last 8 years. dojo.storage is one major step towards the realization of that dream. Today almost no web application has offline support out-of-box. Tomorrow it will be just another feature that people take for granted. There are still much work to be done to make the average web application support offline use easily. But this is a very good start. BTW, I guess some people will probably start calling offline-capable applications web 3.0. Nice work, Brad!
