Musician to musician. I've been playing guitar before a few thousand people. The room is dark except for the glow of my pedals. The song count comes about and it's me that does the intro. Normally DP would've freaked me out but practice, practice, practice and experience has worked for me. After so many DP interactions during performing, I've gotten used to it. It can be done. Someone with DP should definitely take more precautions to be fully prepared and utilize a lot of muscle memory.
