We have a server which inturn interacts with multiple devices each of which has our app running on them. Our server directly interacts with twitter to post messages coming from all these devices. So can our server use xAuth for authentication? I had this doubt because its been mentioned in this link http://dev.twitter.com/pages/auth_overview that xAuth is to be used for single user apps(mobile/desktop). Does this mean that our server will be considered as a web app or something and hence xAuth wont be supported?
