Very pleased with T-Internet-POE

I bought a pair of these, and my first project worked out great. One suggestion I have would be to bring out +5v on the GPIO header. I've got a sensor board that won't run on 3v3, but it turns out you're making +5v on board. My solution was to bodge a wire onto C48/C60 but having it by default would be great!
