This seems like a lot of effort to get a net list given other techniques to deduce what pads are connected (e.g. knowing the most connected net is the ground plane, looking up the pinouts for the ICs, looking at the voltages and signals when the board is powered).
That approach will get you 80% of the way there - which for a lot of applications is next to useless.
The problem is that for a lot of chips there aren't any datasheets available. Sure, something like a memory bus is trivial to trace, but how are you going to reason about Unknown Pin #464 coming from Unlabeled IC #4 which seems to randomly have a 500ms pulse on bootup and every few minutes afterwards?
