eh, I wanted to say that :D Yeah, it seems like the ultimate USB end-device for EMC would be still a PowerPC processor running realtime linux. heh. So we ended up just where we started.
But I really adore the idea of havin a LAN-based system, because LAN is electrically isolated and well insulated, uses twisted pair cables, runs great lenghts and can use switches for traffic switching. Gbit LAN wiht a Gbit switch would be genial for controlling whole manufacturing line from a single PC. More expensive than the parallel port, but still nice. As for the processing power of microcontrollers: DSP processors can have more processing power that a PC processor with less power consumption.
