My 2 cents on the option: I think having a separate option from 
media_encryption is the way to go. As far as the name of the option is 
concerned, I'm fine with what you have here, but I also am partial to 
jbigelow's idea of naming it something like media_encryption_force (and 
reversing what yes/no mean).
