The libre Embedded GNU/Linux Distro.

“libreCMC is a set of fully free embedded Operating Systems for general purpose computers. It aims to give its users freedom and control over the software that runs on their hardware. Most of the hardware that libreCMC supports includes a wide range of routers and some small single board computers.”

This looks interesting and perhaps can make a project for a tech jam to look at.  If anyone is interested perhaps chat at the jam or on IRC.
