Adapter cable block

Hello, my idea is to create a new block on ComputerCraft that acts like a cable and a wired modem. The main purpose is to allow cables to pass a wall without seeing an hole. Or allowing to connect a network under some peripherals that are not an entire block to prevent seeing an hole with the modem and the cable under it. The only way to do so at this time is to connect a computer directly to them, since the computer is big as a true block. With Galacticraft, this kind of cable would be really useful. ^^

CCTweaks adds support for multipart cables - including using hollow covers. I don't know if that solves the problem you want though.
