Working in a school enviroment

We want to be able to use Digital editions in a school enviroment where a student is never setting at the same device and may use 8-10 different devices during the day and even more throughout the week.  The authorization processes is making this very difficult.  Is there a way around the authorization required to use ADE or a way to unautorize and release the book from the device so it can be brought up on another device by that user.
