You can get a DVD player and TV for your car, and you can watch satellite TV on an airplane -- it was only a matter of time before someone made satellite receivers for cars. RaySat's SpeedRay is a two-way satellite communications device that can receive data and TV signals.
The most obvious use is to keep passengers entertained during long car trips and to give RV vacationers constant access to TV and the Internet. The SpeedRay also has uses for emergency and military personnel.
