As long as you only uses the methods in the namespace ExorLive.app, simply called the "Remote Control API", there is no need to ask for authorization. If the user is not logged in, he will be asked to log in. If he is logged in, he will be taken directly to ExorLive when using any of the methods.
The example creates an hidden iframe on the page, which it uses to communicate with the ExorLive application.
This example works fine in Firefox and Chrome, but if you are using Internet Explorer, you will have to turn off Protected Mode or the authorize step will fail with "could not pass back the code".
You will have to authorize before any function below can be used.
