Are there any good books on using  OAuth 2.0 for mobile? 

When we create the API for this site, I want to be able to let developers access the API through mobile apps without needing to access other users passwords or information. Seems like  OAuth is the best solution right now, although it seems a little clunky when working with mobile. 

Also, when we start working on the official app for this site, I will make a new forum so that way users can share source code and suggest updates and improvements all in one place  :)
