I think the problem here is that there's too much syntactic sugar in sessionStorage/localStorage (this is more feedback to HTML5 or WebIDL, and maybe Hixie or others could help to address it).I can easily replace the object (window.sessionStorage={})
The sessionStorage property is readonly so that won't work.
but I can't be told when my sessionStorage is decorated by a new property, because that's not something which is available to JS (gecko has __noSuchMethod__, but there's no watch(sessionStorage, "*", feedback). If there was a way for js objects to be told about property writes then for the most part, they could replace a host's sessionStorage/localStorage with their own object and do what they need. Today, if the HTML5 sessionStorage/localStorage objects relied on (sugar-free) methods only, they wouldn't have a problem. -- No, I'm not advocating this.
Things like watch points aren't really defined if they should work when it comes to host objects I think. And if we used an API like setProperty/getProperty they certainly would not work.
So I don't think the problem here is with the specific API localStorage uses either. But rather with the fact that Scott is trying to deploy a widget implementation in an environment where he is restricted about what the APIs he is implemented are called.
I think in this instance though the problem can be worked around by adding event listeners to the Document listening for 'storage' events. That can be used to then save the data server-side.
