But those cases have mostly been open unauthenticated wifi, no? If I'm understanding this, this provides the courts a traceable way to go after an authenticated person (or at least, a facebook account) rather than just an IP address. I think the courts that have pretended that "IP=person" have done so because they don't have anything better.
