They're going to want to have the choice of keeping their preferences "close to the hip," stored locally on their mobile device or in their desktop browser. They're also going to want the flexibility of keeping their preferences in the cloud, accessible to a wide variety of applications and Web services without having to manage lots of separate profiles, logins, or account information.

This has been a long thread, and some of the background has inevitably gotten lost in the shuffle.
I think the best way to clarify all of this is write up a bit more detail about what we're talking about. I'm going to volunteer to start a wiki page describing the architectural issues for preferences storage in its various forms, and then suggest a plan for next steps. Since we need to move on this soon for FLOE and the Infusion 1.4 release anyway, now seems like the perfect time. Once I've written some more detail in the wiki, we'll have something tangible to discuss.
In the meantime, let me reiterate my position:
* Preferences storage should be about choice: a distributed, cloud-based approach to preferences storage, along with the ability to store preferences locally in the browser or on a USB stick.
* At the moment, OpenID the only solution for distributed single sign-on used by real people on the real Web, so we'll want to be able to work with it in our architecture, despite its flaws.
* Our architecture should absolutely not be tied exclusively to OpenID, nor any other single authentication scheme.

Seems like it, yes.
Here's an example of a local browser preferences storage use case:
"Joey has a computer set up at home. An assistant has helped him get all the assistive technologies he needs installed on it. He's also been helped with the process of setting a GPII preferences profile. Since Joey's computer is perfectly tuned to his needs, it's the system he uses to access the Web most of the time. Joey wants be able to allow certain Web sites to access my styling and UI preferences, so that they can deliver their Web applications in the way he finds easiest to use."
As Rich as pointed out, HTML5 Local Storage and a browser add-on are a good solution to enabling Web applications to transform their user interfaces based on a user's GPII preferences without having to rely on a third-party storage server. As I said in my previous email, it's not a suitable solution for public workstations such as those at libraries or community centres.
Hope this helps,
