Huh? What kinds of events? And if you record position, velocity and 
acceleration, what's left to simulate when your events occur?

I assume you're suggesting that when you get an event you can record it 
like  "add (dx, dy, dz) to the acceleration vector at time t" and then 
when e.g. position or velocity is queried on the object, you integrate 
forward from the last update to the current?

That can make sense for things like computer-controlled entities in the 
world (although I'm not sure why they'd be generating events that do not 
depend in any way on the current state of the entity), so only the parts 
of the world where players are use up CPU cycles... but... uh... it's of 
fairly limited use, I think.

Unless I misunderstood.
