These are not web-apps that can work offline longer than 2 minutes.
Android's GMail app is getting to be as bad.

But otherwise, many imap clients exist as desktop or in-device applications.
I think Tim is asking for something in the middle and the distance is pretty big.

And this is the reason the normal model has been: no security model at all.
Desktop applications have been living well with some web interfacing... installing a web-app could start where desktop applications are then gradually go less demanding?

Android goes somewhat in this direction with its app-security model...

I don't know how well such limits are handled by browsers, I've seen a lot of browser crashes for these reasons. Pointer?

Same thing, the user-warning on slow script is not that limit!

An editor importing a web-page?

Typical state of a young feature: Chrome does it without asking me, Firefox asks me if I want to use my own server ;-).

when you consider the success of app-stores, I think that I do not share this view.
