Add a mechanism to be able to run a script using RPi.GPIO without root 
privileges.

This would be extremely helpful in allowing us to use this great library in a 
web-server context (for example).  Thank you for making this a high priority!

Hello, I am running a Python program which needs GPIO access. How is it 
possible to access GPIO without root rights (sudo)?

I'd be thankful for that, too...

Hi, using subprocess or os.system directly in python, you don't need sudo rights

Hello, you could use a subprocess.call or os.sytem and echo [1|0] under the 
desired PI, you could check 
http://hertaville.com/2012/11/18/introduction-to-accessing-the-raspberry-pis-gpi
o-in-c/, the first part, explain how to interact using bash with GPIO, so you 
should not use RPi.GPIO if you want to use the pins with a non root users. Just 
configure them at startup and then write to the pin using echo, thats it, i 
checked and is working, I have not the code on this computer but using 
subprocess.call on python and inside a "echo 1 > /sys/class/gpio/gpio18/value" 
should be enough.

I've had success in this by creating a copy of my python interpreter binary and 
setting its permissions to run as root (cp python-2.7 python-2.7_root; chmod 
u+s python-2.7_root) and then telling my script to use that interpreter with #! 
/usr/bin/python-2.7_root. It's a security risk, to be sure, but it works. I 
haven't gotten it to work with service scripts in Kodi/XBMC though, as those 
scripts are executed differently it seems.
