I finally got my iPad Camera Connection Kit in the mail and started right away working on integrating the USB foot pedal I bought. It was easier than I thought it would be.  Check out the YouTube video demo below.

I'm hoping to ship this in version 1.3.  To make this work, you'll need the Apple iPad Camera Connection Kit and the Versa Dual Foot Pedal from PedalPax.com

Take a look and tell me what you think!
