inverse matrix transform - Using transform difference between an original and an altered point animation to re-apply this to a group of other animated points

[mackerBaehr]

Hi
I am looking for a way to let a group of points further behave as a child of another point, after this masterpoint has been altered (say through noise or other secondary effects). 
The transformeffect on this masterpoint should be re-applied to the other point group, with the masterpoint itself as a pivotpoint
Something gives me a hunch that inverse matrix transform might do it but I am not getting very far with it.

I hope someone could point me in the proper direction. 
I have a file attached which should abstract the idea

Thanks for the thinks
