The Cook? Those who provide technology or software that facilitates copyright infringement. In our recent history, what became the VCR and allowed copying of video for use when we wanted, a precursor to Tivo and DVR's, raised the question of copying for personal use without paying a license fee (even though some copying was obviously not for personal use, but for replicating for others). At one one time the Lover, the content providers like movie and recording studios, opposed the use of VCR's without payment to them, a rather luddite approach. The Cooks today are file sharing services and internet providers and others who provide new technology that facilitate copying.
The Thief? Usually a child or youth or student or young adult who just wants his or her content, and sees an opportunity to get it inexpensively. This is a candy store, and few of the thieves see themselves as stealing.
The Wife? The Court system, who has to sort this mess out. And the primary wife is the Ninth Circuit, the home of the industry seeking protection. One article explains the current conundrum:
The most prominent lawsuits have been brought against vendors of peer-to-peer file sharing software—Napster, Aimster, and Grokster—who have been held liable under the judicial doctrines of vicarious liability and contributory infringement for the copyright violations committed by their users. Although these secondary liability doctrines are well established in copyright law, the Napster and Aimster decisions have expanded the role that illicit intent to profit from others’ copyrighted works plays in determining liability. The expanded scrutiny of intent makes it difficult for developers of copying and distribution technologies to predict their potential liability and undermines the limited immunity for the development of useful technologies that the Supreme Court established in its Sony decision.Sverker K.

So, what approaches are being used? My bias is simple: the economic consequences of the law must be evaluated, and the legal rules that promote the most benefit for society chosen. This is quite different than a "property law" analysis urged by copyright owners; but, copyright law already imposes blanket licenses at times.
We'll think more about this in coming days.
