This looks to be a fantastic breakthrough. I think Brian A. will get a kick out of the storage system he describes... it sounds awfully familiar. ;-)

I'm proud to announce the immediate availability of dojo.storage and a new web-based editor named Moxie.

Imagine if web applications could store megabytes of data on the client-side, in the browser, both persistently and securely. No server needed.

I'm going to have to implement this for Conversant. Soon.

(Thanks for the link, Daniel.)
