I start with Frank Easterbrook's question, as relayed by Larry Lessig at the beginning of "The Law of the Horse": Is "Internet Law" no more coherent a subject than the "Law of the Horse"? Then I do each of the modules -- but after each case, asking, what is it about the Internet (if anything) that makes this case different? Is a new rule needed? Or can you simply apply existing trademark/jurisdiction/First Amendment law here? What method do you use to decide that question? If there's anything unique about cyberlaw, it lies in the answer to this meta-question.
