Our high school teachers sometimes play an audiobook in the classroom for students to hear. 

Is there a legal streaming solution for this? If I purchased a legal audio version of the book - other than purchasing it through Follett and accessing it through the catalog, I can't find a way for teachers to access it in their classrooms. It needs to be single user. We don't want multiple people all logging into one account - that is not ethically sound. Audible has no interest in partnering with schools. They told me that very directly the last time I tried to talk to them.

Short of having books on CD and a boombox, I can't find a way to have audiobooks in the library for teachers to use in their classes.

Any wisdom from the masses?
