One problem I've always had with doing peer instruction using the CPS software from eInstruction is that you can either set it so that the answer distribution shows up immediately on the slide after the clicker question is closed, or not, and that applies for the entire session. There is no easy way for the instructor to see what the answer distribution is without also showing that distribution to the class. This means that if the answer distribution is mixed and I want to do peer instruction, students will also have seen the answer distribution and that can create issues with students assuming that whatever answer got the highest number of responses must be correct.
At a recent workshop, I mentioned this issue and Mike Salemi suggested that I blank or freeze the projector before the answer distribution shows up; that way, I can see the distribution on the monitor at the podium but the students won't see it. I have no idea why that never occurred to me before but all I could think of was, "Duh! Of course!"
