Watch the Keith Richards online guitar lesson by Jeff McErlain from Kings of Tone
So now you have the open tuning bug and you want to start using them on a gig, awesome! Now the downside, I highly recommend you bring another guitar for open tunings. Why? Well it will certainly make your set flow much more smoothly because you won't be tuning on stage. Also I recommend you keep open tunings to guitars with fixed bridges such as a Telecaster because with the changing tensions a floating bridge will keep moving making your life very difficult!
