"via" comes from latin, it means " a place to travel trough".

For example in Spain "autovia" means via for autos or "tranvia" means a vehicle that goes over rails. "Via pecuaria" means a road for animal transport.

You can do lots of useful things with just two layers. We prototype professional electronics in house with just two layers and modules(over a big area), then shrink the design, use more layers and get it done using a professional service.
