I havent done pairing interviews but I have tried giving candidates some started code and having them develop a solution based on that. One piece of logistical advice here: keep different kinds of keyboards/IDEs available. I use a mac and I interviewed a candidate who wasnt comfortable with the mac keyboard. In an interview situation where a person is already slightly nervous the last thing you want is for them to be worrying about keyboard shortcuts!
