Scott Rust, senior design engineer at Neosonik, pushes a cart holding an LCD TV down the driveway. We pass a semi-constructed 1967 Mustang, a boat trailer and a couple of incomplete trucks. The guys at the neighboring warehouse are discussing a coming storm.

We went 200 feet, through six rooms and three external walls" before the signal got a little weak and caused the picture to get pixilated, he said. "Often, people want me to unplug the TV to make sure it isn't power line networking."
