After an hour of hacking (even I'm amazed it only took an hour!) I have managed to get a very basic TCP/IP client/server system working in Gentoox Loader. For now, its unreleased and does nothing more than send out a "GET / HTTP/1.0" line and read the response (poorly). The inspiration for doing this came from a forum post. The eventual idea is for Gentoox Loader to be able to download an initrd and kernel from a server which will then launch an installer meaning that the installation will be entirely diskless (oooh, ahh!). Anyway, I'll work on this more later. Enjoy this photo as proof of concept:
