Google Talk OAuth authentication

[dsample]

I'm trying to connect to Google Talk using their OAuth2.0 login. I've obtained the access token, but I can't work out how to create the SASL Auth request.

I've seen the X-Facebook-Platform, but I can't infer from that what I'd need to do to create the relevant Google Talk equivalent.

Is there an easy way to achieve this?

I've got the functionality for X-OAUTH2 working in my forked version, I've tried to put it in cleanly, but it didn't detect the requirement for the X-OAUTH2 mechanism so I had to overload the client.auth method to allow the mechanism to be specified... not sure if that's the way you'd want it done if you pull my commits.
