I don’t get it. I think motion blur works exactly the same for expression controlled animation as it does for keyframed animation. Doesn’t it?

Precompose your layer (with “Move all attributes…”) then apply the mask.

With the expression I mentioned before, the layers would position themselves in 3D space – you don’t need to run a ram preview to see it happen (assuming you’ve got the camera positioned correctly).
You could do the same thing with a script. There would be a number of ways to set it up, but you could have it look for all the selected layers and position them in 3D space for you.
For your application either method should work fine. I like expressions because I find them easier to write and debug, and when you change them you see the results immediately.

Yeah, now you’re into one of those areas that expressions are not particulary well suited for. You’d need an expression that integrates the speed of the other layer’s movement. Doable, but kind of a pain.

I’m not sure exactly what you’re asking, but this position expression might help:
offset = 320;
value + [0,0,(index-1)*offset]Dan

The expression works like a speedometer – as the moving layer slows down, the rotation returns to zero. When the moving layer is at a constant velocity, the rotating layer stops rotating at some value away from zero.
It sounds like you may after something entirely different. Do you want the rotation speed of one layer related to the positional speed of the other layer?
