I would consider looking into the Federated Login API and leveraging OpenId to authenticate your users. You can use oAuth to access the user's data. If you're using Java, you can reference the step2 project, which combines OpenId+oAuth. With this, you would have a single instance of your app, and you would manage the authentication within the application. You would also be responsible for making sure that the user data stays separated, as necessary since all domains that use the will share the same datastore.
