I am creating a rails application that I also wish to work as a native app on the iPhone and Android. In order to facilitate this, I was thinking about becoming an OAuth provider. Is there a rails OAuth plugin that will work like this, or is there a better solution to protect the API?
Note: I have found pelle's OAuth plugin, and it looks very robust, but it looks like it requires a callback URI, which the native apps would not have. Is it possible to just convert this over without much trouble?
