Offline access to web services (email, editing, …) is the next Big Thing (I’m sure Google must be working hard on this). SocialText seems to have an interesting approach: embed the application in the html (as js), download it, use it to edit and such, and when you’re back online synch back. (If I understand the approach correctly). That’s smart, it doesn’t require a new browser or anything. Could Gmail do this for me?
