The XKCD display box and router converts the internet wifi into a local ethernet.

Right next to it is a mini-network consisting my my freedombox, running as an access point, and bridging via ethernet to the the git-annex-logoed OLimeX computer.

I was using this today to get a clean Debian installed on the Lime (it came with a messy debian preinstalled), and investigate what needs to be done to support it in d-i. https://lists.debian.org/debian-arm/2014/08/msg00219.html

I was surprised I managed to get the kernel, filesystem, and even u-boot replaced. Mostly because I don't have a serial cable for this box, so the only access was over wifi-to-ethernet, and via looking at the microsd card after it booted! Only 2 twice did it fail to boot at all, luckily. :)
