The Fabs are different in her performance. Mainly you can have VIAs
between every arbitrary layers. You can also have two VIAs on the same
point in different layers. You just need the drill-file for each
Via-Type (Layer_3-5.drill, Layer_1-2.drill ). 
The Software-Tool shall be universal at all.
The fabs do, what we wish.

This is not a limit for fantasy.

I see, this are many things.
The Exporter is one of the easy problem.

What is about the RAT?
