Account Chooser - for the next generation of web sign in

Think long and hard before you implement something like this on your website. Implementing the bog-standard login system is a one-morning task for any engineer capable of writing a web app. Supporting multiple logins well can occupy teams of competent developers continuously and they will still screw it up. The underlying OpenID/etc protocols are some of the worst designed you will ever have the misfortune of working with. Your users will hate the experience of using them on your site, largely because a) they do not understand them, b) they do not solve a real user problem, and c) when you screw up your implementation -- and you will -- you will lock them out of their accounts.

I don't see anything in the GITkit documentation where Google promises any kind of uptime number or notification window before disabling the service and leaving you with no way† for your users to authenticate to your service.

† You could try get them to do a password recovery procedure since you kept their email address, but I'd rather not send out an "I'm sorry, we lost your password." message to customers.

Perhaps a little premature post: looking at http://accountchooser.com/how.html (as of 8/29 at 12:23pm) there are a host of "image coming soon" placeholders. At least finish up your first sentence before broadcasting.

The site is going fairly unresponsive, is this a login service like Janrain RPX or is this more akin to a component that you integrate yourself, like AuthLogic?

Tried signing in to the "Sample Store" on the site using Gmail, but the attempt merely resulted in a blank popup window on Firefox 6. It's a shame because it looked quite promising until then.

there's the official Account Chooser Working Group Charter proposal announcement - https://sites.google.com/site/oauthgoog/workinggroupcharter/...

How are they different from OpenID?

is that opencart extension available somewhere? would be great to release it.
