Hello! I'm a bit new to Xbian and coding, but I'll try to make myself understood.

So I'm doing this project at school. I have a eGalax touch screen hooked up to my RPi. Via the GPIO of the Pi I have jumper cables hooked up to a relay board.
I want to use the touch screen to control the relay board.
So first off I flashed the RPi with Raspbian and made a simple Python script to make sure I could control the relay. Everything went just fine.
So now I've been chasing for some kind of UI to be able to control the relay in Xbian(or XBMC overall) instead.
I need a few things to be clear.
Is Xbian running as superuser? Is there anyway to make it run as superuser? Is there any other way to access the GPIO without running as superuser?
And the last question, is there anyone out there, who is able to make a simple addon to control the GPIO pins, or at least know how it could be made?!
Thanks in advanced,
Arvid
