Ben Laurie from Google responded to my post on Google Account Authentication: two steps forward, one step back. A few comments that I’d like to respond to:

Duh, of course you have to provide a Google credential, you’re going to access a Google service. What kind of credential did you expect to present? Your Yahoo login?

Uh, actually, yes. That is the idea behind Identity 2.0, that I could use my Yahoo login to authenticate to Google and to access Google services.

How does allowing applications to access a user’s Google services deepen anything? Did Dick actually read what these services do?

Yes, I did read with great interest what the services do. As for why this deepens the identity silo, these new identity APIs make it easy for non-Google applications to consume Google services, but it is tied to the user’s Google credential, increasing the value of that Google credential, but creating a bigger barrier to services similar to Google’s, and increasing the users reliance on the Google credentials. Good for Google, but starts to reduce user’s options.

As of right now, what are the options? Is there any mature, reliable, secure identity federation mechanism that’s widely used?

Ben is correct, there is no mature, reliable, secure identity federation mechanism that’s widely used. But that has not stopped Microsoft from working to create one and announcing that they will be using it in their products in the future. Google could participate in defining Identity 2.0 architectures and make them widely used because they are Google.
