xxxxxToMover() and xxxxxToObservers() methods should be only used on a unit controlled & moved by a player (as in direct client control: possess, vehicule,..).
ToMover() to send a packet to the client (asking for confirmation before acting the change) and ToObservers once the change has been acted and should be broadcasted to the other players around (the observers).
 
xxxxxToAll() method should be used on a unit controlled & moved by the server (@todo note to self: does a player moved unit under the control of a temporary disorient (Scatter Shot eg) or fear fall into this category? EDIT: by looking at the effects of Psychic Scream (10890), the answer is yes)
