I'm still hoping for someone to build a SBC like the RPi that takes POE for power. USB is convenient for general use, sure, but for something like this cluster it would be ideal to have a single wire in and out.
Unfortunately it's probably a chicken-and-egg thing, where POE is too expensive until a lot of boards support it, and boards won't support it because it's too expensive.
