I have a potential client project coming up where they will need to access a user's webcam and record video and audio from it. They'll want this to work in modern desktop browsers (let's say latest Chrome, Firefox, Safari, IE10+). At this point in time I don't believe it's possible to do this with HTML5 technologies alone.
