Superluminal Elf Radio

Santa’s gift tour is a headache for children every year: How does he manage to visit every child in the world in a single night? But Santa’s travel speed is not the only problem. I wonder: how does he know if the child whose chimney, balcony or front door he is standing in front of has been naughty or nice? Does he carry around the naughty-nice-list in paper form? Is he in radio contact with the North Pole? Or does he have a completely different method? We will ask the question: Is communication faster than the speed of light possible?
