the only issue here is with abusive clients. since federation allows for different clients (apps) to be used to access the information, an abusive app could download the movies /music/etc illegally for sharing or even profit. this can be mitigated by sellers/artists/producers only allowing certain apps, or perhaps blacklisting certain apps instead (in order to allow the user to have more choice). this issue could probably also be solved in other ways, this is just one idea.
