But many of the recently discussed features are linked together. If we don't 
discuss all, we will implement only some of them and recognize later that our 
solution doesn't fit with the others.

I don't want to avoid it.
Once more my idea: Each script has a initialization part that is called when 
the animation starts. It is up to the user to initialize all data at the 
beginning of the animation he changes with scripting.

No, the program calculates the animation stepwise until the chosen time is 
reached. That will take some time, but can't be avoided.

You can only calculate the scene immediately if all translations etc are only 
a function of the time, but that will not be the default case.
