quicktime video output component

Basically I'm thinking about a patch that has one "Image" input and sends the incoming image data to a video output device, using the Quicktime video output component. I use a Blackmagic Design Intensity Pro video card, but it should work with every DV device as well.

The main appeal of this patch would be to use a dedicated video interface for presentations that is not part of the extended desktop, thus avoiding embarrassing situations like an application opening a window on the projector. Another idea would be to use some cheap DV cameras as output devices for separate animations and connect them to a pile of TVs on stage, for visual effect. There are probably tons of possibilities to use this.
