What about my case: I run a software training company. We provide streaming access to recordings made of the live session for which a student purchased a seat. Pay for a four day class, and you can stream the recording of that four day class for, at the least, 18 months. Why 18 months? That's all we promise, ideas end up being available for longer - five years and counting now - and in 18 months the class tends to have changed enough that we'd rather you just attend again (for free, if it's online). Do you have the right to pirate the videos that my students paid for? Do they have the right to share it with people who didn't attend the course, and are thus missing the context of the classroom experience (and the web site where updated materials/code samples are dispensed)?
