My understanding is that this computer program (accessing the webcam remotely) is standand anti-theft material on all MAC laptops. The idea is that if the laptop is stolen, the owner can contact (not sure whom) to active the program to help locate the thief & laptop. Big brother starts small in helpful ways.
Strikes me as pretty worthless. Presumably this is known to most computer thieves, who would just tape something over the camera lens to disable it.
