That's what I meant by lights-out capacity.
Intel AMT out-of-band management is a premium feature that commands a price. Investigations of ME have revealed that the necessary hardware is present in all Intel systems. To take control of it, remove the potential for alphabet agency implants, and use it to add functionality that Intel would charge for would be a satisfying "fuck you" to Intel for kikeing our systems in the first place.
OpenWRT/LEDE is about the most minimal Linux distro possible, totally user-configurable and would fit in the SPI flash. If we could manage to get it (or the GNU de-blobbed version, Librecmc, as >>829156 suggested) installed in place of the ME kikeware, then the next challenge would be finding or writing the software to redirect keyboard, mouse and video to be served over the network as some remote protocol. I suspect SPICE would be most suitable for this application.
