Can I support Google's multiple sign-in with App Engine?

Question

Currently, to switch between multiple Google Accounts in my App Engine app, users have to logout and login with each Google account. This messes up the various Google tools they have open in other tabs if they are using the multiple sign-in feature.

Is there any way to offer users the option to switch between multiple Google accounts in my App? Like users can now do in gmail etc. http://support.google.com/accounts/bin/answer.py?hl=en&answer=1721977

I've had a look around but can't find anyone else doing this yet, but apologies if I've missed this.

I'm using App Engine with Python and the standard Users Service.

Unfortunately this is not supported. I think it is worth filing a feature request at our issue tracker.
