Is there a distinction between sharing among peers and using other peoples work for your own profit? Is it possible to make a difference how copyright laws are applied to personal/private use and for organizations/corporations? How is software and "culture" as in music/movies different? If any, should we make that those distinctions visible in IP-laws?
