The readme says there is also an additional device that can be used for copying the ERPROM, instead of doing it via the computer. It would be possible to integrate the copier in the firewall dongle but that would mean having a microcontroller in each device that is just used once, driving the unit cost and the size up. The firewall dongle as it is is just holds an EEPROM, ancillary components, and the video passthrough traces.
