We are nearing a point where we will be posting a patches for Shindig for both the OAuth 2.0 service provider and Java-side client support. The client support is being worked on by Adam Clarke and Li Xu and uses some of the proposed ModulePrefs changes ( http://code.google.com/p/opensocial-resources/issues/detail?id=1209).
They have also been contributing code to the same fork of Shindig in github where Eric and I have been working. https://github.com/mgmarum/shindig Expect Shindig patches to be available by Friday.
