Idea of new Offset Addon (to : Script Writer)

I have an idea about new addons,
I cant make this because I dont know python.
The idea is simple,just make Object A follow
Object B like “Add to parent(crtl p)” control but late without using keyframe…

*sorry for bad english

This is video link to some example in other application…
videocopilot.net/tutorials/3d_offset/ this tutorial explain what i means…

vimeo.com/19612971 this show how it done in cinema 4d

vimeo.com/15461070 (00:55 second show transition using this idea)

youtube.com/watch?v=Bje4sEErSAc this is my idea try
recreate the add on (fake)…but it have some basic idea…
