[Cthulhu_]

And in Eve, this is even more feasible because, unlike an FPS or even MMO's like WoW, movement is generally slow and controlled. You don't have direct control over your ship; instead, you can only issue commands like 'head for this waypoint', 'orbit this point of interest', etcetera. This would, I think, greatly simplify server communication of movement and such, compared to direct user input where they could change their orientation much more suddenly.
