It works very well for objects that follow real world physics. One
challenge with games is that players have been conditioned by FPSs
and console games to expect that their avatar has no momentum: 0-60
in one keypress, zero turning radius, starts and stops instantly.
This makes position prediction much harder than if there are limits
on acceleration. Even a quarter to half second of ramp up/down time
on speed, and a reasonable limit on turning speed, would help a
lot--but unless they're in vehicles, players will probably complain
that motion isn't responsive enough.

Well, some of the basic techniques (such as Kalman filters) go as
far back as 1960. I believe that the first application to online
games was Quakeworld, but I don't recall when it was released.
