Power Over Ethernet - Powering Remote Arduino's

Several of my projects use Ethernet to communicate data back to a server or internet connection. Our Web Enabled Weather Server for one. I've decided to power the remote arduino and sensor board over the ethernet connection. Common Power Over Ethernet solutions send 48vdc over the spare Ethernet pairs (others send the power over the data pairs as well). The solution I have chosen takes the Ethernet signal from my router, injects the power, and on the other end, strips the power back out before supplying the Ethernet connection to the Arduino. It contains a 48v to 12v/9v/5v DC-DC converter.
