Flash - user drawing and sound capture

I need a flash application developed to run in a browser that uses the user's microphone to capture audio and simultaneously record mouse click and drags to record simple drawings on top of a jpeg image. This 'recording' should then be able to be played back to hear what the user was saying when he/she was drawing (essentially circling parts of the jpeg image to give instructions): The application: a) loads a specified jpeg file (800x600) and displays it b) user presses record button c) user accepts Flash security alert to start capturing audio from the user's mic d) user can click and drag mouse to draw on top of the jpeg while talking e) recording stops in 1 minute or when user presses the 'stop' button The recording is saved as a swf file or if you are simply saving the audio and the drawing as coordinates etc, then another sfw to be able to load this recording and play it back as it was recorded. This will be put on a website for users to review jpeg files. No emphasis on design of the application. It just needs to be developed with the funtionality at this stage. We will implement design later. Flash plugin v10 can be used and ActionScript 2 or 3 can be used. Please let me know your approach and any challenge
