the BitTorrent case study:

Why haven't the record companies or film studios tried to shut down BitTorrent? What actions by BitTorrent would make them more or less likely to sue?

Does DCM-Doll Capital Management, the venture capital firm that funded BitTorrent, have any potential liability for copyright infringement?

What could Napster, Hummer Winblad, and Grokster have done to have avoided suit, or to have given them a stronger position with respect to the legal actions that unfolded?

Does Google's library search project or its image search feature violate the rights of the copyright holders of the content Google digitizes? If you were CEO of Google, what assurance would you want from counsel before proceeding?
