EFF has an information piece on efforts to pass a series of 'super-DMCA' laws in a numer of states throughout the US:

The super-DMCA bills would regulate the possession, development and use of "communication devices" and "unlawful access devices." A "communication device" is virtually any electronic device you might connect to any communication service. The definition of "unlawful communication device" is somewhat narrower, sweeping in any device that is "primarily designed, developed, …possessed, used or offered… for the purpose of defeating or circumventing" a technological protection measure used to protect a communication services.

The proposed bills generally prohibit four categories of activity:

1. Possession, development, distribution or use of any "communication device" in connection with a communication service without the express authorization of the service provider.
2. Concealing the origin or destination of any communication from the communication service provider.
3. Possession, development, distribution or use of any "unlawful access device."
4. Preparation or publication of any "plans or instructions" for making any device having reason to know that such a device will be used to violate the other prohibitions.

These proposals dramatically expand the power of entertainment companies, ISPs, cable companies and others to control what you can and can't connect to the services that you pay for. If enacted, they will slow innovation, impair competition and seriously undermine a consumer's right to choose what technologies they use in their homes.
