wouldn't this cause many more significant issues, if one person is flying to another planet or moon the speed of that object must also be adjusted in order to account for the fact the vessel is moving faster, but when this is done then another player attempting some maneuver has to deal with those objects moving at faster rates and everything, basically when somebody is warping all other locations in the game cannot be used until that person has completed their maneuver. multiplayer would be pointless if only one person could actually do something at a time.
