I made a wonderful discovery today. If you have the AirServer software, it now allows screencasting recording of your iPad. Requirements are a Macbook, AirServer software and updated iPad. When I made my first test recording I noticed the microphone is automatically muted, but a quick click on the AirServer screen on your Macbook allows the audio recording to capture simultaneously.

This will be a great tool to demo activities for teachers and students!
