Hampton Jitney runs its buses not just between Manhattan and its antipodes in Long Island: The company also runs a car-and-bus shuttle (you plus a car) down to Florida's east and west coasts, with an Ambassador option. It's $1,528 each way for two people in a 31-person bus and their car (on car trailers), and now the company also offers Wi-Fi, as it does on its New York fleet.
Spain's Renfe rail operator will add Wi-Fi: They've been testing a service they plan to roll out using satellite Internet access.
