This looks real interesting. I presume you are using an Ethernet interface through the micro USB for inter node communications. Can you provide information about power requirements?
Demand is very high for the Zero. Please do not make the biggest mistake you can make in business, by doing a knee jerk ramp up of production. If the capacity can't cover the need, either ask people to wait, or raise the price. Performing emergency production increases is the quickest way to kill any profit margin you had. Especially if it means starting a new line or switching over a line from another product.
