This is a board that incorporates a SFP port, two NICs along with additional support. Built on the lines of the Raspberry Pi, it allows you to use your networking distro of choice, albeit one which has support for the device. Frankly, looks very interesting, and if there are distros compiled for the hardware, we could design our own routers, rather than be stuck with ones that are sold by the companies.
Of course it goes without saying that it could be multipurpose into anything thats supported. Solid run appears to be doing a entry level version and a pro version.
