Law is often mentioned indirectly in the concern about Free Software, and the GPL v.3's viral structure can be considered a kind of legal hacking, so it's around.
For books- Plato's Dialogues, Machiavelli's the prince, and the Tao Te Ching are good places to start. They each illustrate a different culture's ideas about legal frameworks by considering different rational focuses of moral consideration. Such a varied approach is a useful way to jump in if you're just starting to think about law, since it illustrates the way that law is a logical enterprise by extrapolating from crazy different premises.
Recently I've also discovered Eben Moglen, who's a lawyer and a technologist who gives very interesting talks.
