Flip Support from Administration

I just wrapped up a presentation about Flipping the Classroom at UCET2013. I did a similar presentation at Suecon in October and there were about 15 teacher in that presentation. This time I did two presentations and they were each filled with teachers sitting on the floor. I went over the basics of what a traditional flipped classroom looks like and then we talked about changing the traditional classroom paradigm of lecture to student centered discussion and investigation of concepts. As I talked and showed how I run my classroom, the teachers were very receptive. In the end I told them that my flipped classroom is an example of what it can look like. It has its problems like most classrooms. But the one thing I want them to take away is to think about how they want their classroom to look like. I posed this question, "What is the best use of your classroom time with your students?"
The one problem that I heard over and over during and after the presentation was about getting administrator help. I have not had much problem with this new use my principal is very supportive in what we do. She wished that more teachers in our school would give it a good look. I say wished because my present principal is retiring. I know the new principal and I am hoping for the best that she will be as supportive in our ideas. So what do you do to get support from your principal? What suggestions do you have to offer these beginning flippers?
