I think the main problem might be integrating with the camera app - I'm not sure if it actually send notifications for other app when a picture gets taken. You may want to look for an Open Source camera app that you can modify. The IOIO side of things should be straightforward. You'll probably need to use Open Accessory in order to have reasonable synchronization between the flash and shutter, and may need to spend efforts figuring out the correct timing.
