Warm-Up Videos and CDs

I will be uploading some videos from some of my students lessons here on this site. We will begin with warm-ups. I am curious to know how many (if any) of you would be interested in purchasing a warm-up cd. I have been thinking for sometime of creating a simple to follow warm-up cd that you can use at any time - before a performance, in the car, at home, etc. If this might be something you would be interested in, please comment and let me know what would work best for you. If you have specific ideas, feel free to let me know.
