Hah, I have an even better idea. I know you won't read the full thread, 
not even my summary and/or won't try very hard to understand the point 
about using histry (tagging or not) and what to do when that's not 
available.

Instead, write down how this specific feature would _exactly_ work in your 
dream PCB. You don't need to write code and you don't need to describe any 
more feature than needed to understand how you would resolve shorts. Then 
I will try to show you cases on which it doesn't work (there will be cases 
as your approach can't read the mind of the user either). I suspect these 
cases would be similar to the ones where the history based approach breaks 
(be it true history or tagging).
