A virtual host usually has a fullweight Linux kernel - that's a lot of bloat that sits unused; a RPi is actually a fairly powerful computer, with all sorts of complicated, fancy extras (USB? Bluetooth? GPIO ports?) This is a start, but it's still far from minimal: https://github.com/ovidiucp/TinyWebServer https://github.com/ovidiucp/TinyWebServer - after all, even an Arduino is a general-purpose computer based on a chip called ATmega328P; note the mega- infix. This is a much tinier controller from the same manufacturer - only about 10x more powerful than the computers that put men on the Moon. That's fairly minimal by today's standards...but it's still possible to go deeper: https://hackaday.com/2014/08/29/bit-banging-ethernet-on-an-attiny85/ https://hackaday.com/2014/08/29/bit-banging-ethernet-on-an-a... (edit: I overestimated the AGC by an order of magnitude)
