This relates to the Routing 360.. basically I'm imagining something that can do professional board design (think Eagle but without the horrible UI; closer to the 123d circuits but for more serious / production board design)
The ideal would be something that integrates into assemblies, lets users design the board (including layers and silkscreen), place the connectors and components (in a way that can be exported for production with a pick-n-place) and then let components integrate with cable / harness routing.
Ideally down the road it would dovetail into a complete mechatronics system that would let users build working simulations of products that behave like physical systems (all the way from an ARM (/other) CPU simulator to actuators and mechanical linkages).
Even more pie-in-the-sky would be to eventually include thermal and acoustic simulations in the cloud.
