Currently I am forced to use Dynamic Objects which is server side versus FBX Animations which would be client sides, because I want to control playback speed of the animation (i.e. how fast an object spins or moves) based on things I control via a script. If the Playback Speed and Start at Offset that you currently set on the properties on the scene object were exposed via the API I could control them and then use the more efficient Client Side Animations. Would solve a lot of the problems people have with having too many dynamic objects that are only dynamic objects because they want to move them around (i.e. they really don't care about the physics engine, in fact the physics engine is often their enemy).
