If you ever had a chance to work in a large industrial type environment, you'd see just how networked everything is. I used to work at a fiber optic cable mfg plant. Each tiny little solenoid, probe, sensor, heater, etc on the manufacturing line was actually a networked device that we plugged into a Programmable Line Controller. The PLCs we used were programmed and continuously controlled with a Windows 2000-based PC. Each of the PC's were in turn connected to the rest of our office network. Now, I was able to access certain office computers via the internet and I'm a moron when it comes to hacking. I couldn't hack my way out of a cornfield. But I could certainly imagine that if you had a little insider knowledge or some hacker-savant knowledge, you could run the extruders from your laptop while sitting on the John in your apartment's bathroom!

who knows how everything else is connected.
