what is so frustrating is that Google don't actually seem to support OpenID or OAuth the other way round. Why can't I log into Google Docs with a company OpenID account? Why can't Google Google Docs pull company data using OAuth? They support it as long as they are the provider. But in a commercial setting the business itself is the legally culpable provider of authentication and authorization and would be absolutely crazy to put it in the cloud in the way that Google are begging them to do.
