GM had it on at the auto expo
GM had a tavera fitted with the sat tv system at the Auto expo, cost was 80k more over a normal tavera.
I have worked on the SAT TV system you mentioned on Kingfisher airlines, and it needs a GPS input to get the position and heading of the aircraft,( in this case the car ) , and calculates where is it exactly, and in which direction to point the antenna to receive the signal.
Its pretty complicated for aircrafts, though they turn and bank less frequently than cars ( change in direction of travel ) because there is about a seconds lag for the antenna to respond to the change in direction and be rotated.
There are special servo motors fitted, which rotate it in azimuth and elevation to ensure that it remains pointing in the direction of the satellite.
Its possible on a miniature level for a car, but i feel its gonna be successful only on the open highways, where there are no obstructions on the sides, like tall buildings, trees etc, and the vehicle will not be doing so many direction changes as well.
Imagine if you were driving in a city, and had to change directions of travel frequently, which is normal, doing roundabouts, and u turns, and the antenna system would just get messed up tryin to align itself.
My 2 cents..

Sat TV is now available for cars. However the price of the unit is quite high, may go down with time. More details @ Dish Tv India: Watch Live TV in Your Car anywhere in India
