Unfortunately, there is nothing preventing the law from being applied in your 'scary' scenario. Additionally, if I share my password with my wife, and her sister 'borrows' it from my wife, and she gives it to three friends, and they each give it to three friends, who is responsible under this law? How do you prove it? Also, it is just really poor business to solve a problem using legislation which could easily be solved using software. This law may even be in conflict with the licensing agreements between Netflix and the studios. If Netflix and a studio had worked out an arrangement where up to 4 simultaneous users can stream from a single account, who is the Tennessee legislature to declare otherwise. This could be an interstate commerce issue, too.
