PCB design

Idly read an article in Electronics Times today that discussed a PCB design package that allows several designers to work on one PCB at the same time. Interesting idea, though their example was a VME interface on a 16-layer(!) PCB with 12,500 vias(!!) being designed by two people... Wouldn't surprise us if one person could have done the same job in a fraction of the time using four layers and a few hundred vias. Ho hum, I suppose it was only a matter of time before software inefficiency clawed its way into hardware design. Ah, progress...
