  • receiving, from the first device, a first request to set up a position-sharing relationship between the first and second users;

    transmitting a second request to the second device, the second request inviting the second user to accept the position-sharing relationship;

    receiving a message from the second device indicating acceptance of the position-sharing relationship;

    establishing the position-sharing relationship responsive to the acceptance;

    transmitting the first position data to the second device and the second position data to the first device;

    receiving updated first position data from the first device and updated second position data from the second device; and

    transmitting the updated first position data to the second device and the updated second position data to the first device;

    wherein the second user is one of multiple buddies of the first user, each buddy being associated with a corresponding mobile device, including the second device, the method further comprising;

    noting position data for each of the mobile devices, including the second position data;

    calculating a center of gravity for the position data; and
