Launched in September by Rhode Island-based KVH Industries, TracNet brings the Internet to the installed screens in a car, truck, RV or boat. It also turns the entire vehicle into a wireless hot spot, so passengers can use their laptops to go online. While TracNet is still very new, KVH spokesman Chris Watson said there has been interest from owners of recreational vehicles and boats. He also predicted the service would be a hit with car services, which see it as a way to provide a new convenience for customers.
