>We use a magjack that supports Power over Ethernet (PoE), and bring the relevant signals to a new 4-pin header. We will shortly launch a PoE HAT which can generate the 5V necessary to power the Raspberry Pi from the 48V PoE supply.
This is nice though I personally wish they used the same Silvertel PoE module as Arduino which you just solder onto the board. Plus their PoE hat has a spinning fan.
