Just to clearify: I never spoke about implementations.
I always spoke about interfaces to define in this Standard: adoption and
implementation is a "personal" step.
Neither the usage of a server side component nor a direct client side
javascript extension was in my target.

If this matter was already clear, then ignore this email ;)

Hmm.. i'm a bit confused. My proposal was to use a server side backend
for the .localStorage API. This would mean that there is no need to
introduce a new API.

>From my understanding of the original issue that was brought up in this
thread, using a separate API rather than .localStorage would only be a
short term solution, until browsers start natively supporting the widget
API. So that does not seem like a good solution.

However it seems possible to use other solutions to implement a server
side backend for localStorage by using the callbacks defined in the
HTML5 spec.
