Live video of your desktop.

So I was trying to explain design-y things to someone earlier and I had to keep making pictures and uploading them and that was slow and annoying. This is like video-chat, except the video is focused on your desktop. Live feed of your desktop. So if a designer is showing work to his copywriter, for instant, relevance, etc., they can move things left and right and change colors and their partner can see and comment on the changes over many distances, rather than saving as pictures and sending, saving as pictures and sending.
