Development of Creative Commons licenses

[Scott Johnston <johnston AT vectaport.com>]

Has there been discussion at Creative Commons (or elsewhere) of 
developing a license that makes a distinction between public and 
private copying?  Something that extends the fair-use privileges 
protected by the Sony video tape decision to allow a person to 
privately distribute copies to their associates, but forbids them from 
making it available to the public?
