<< Thought you could do that with alot of digital cameras.
Im not sure if its fast enough over the serial interface, but there is a video out on the camera itself >>
You can with a lot of them, but the DC3200 isn't one of them. The video-out on the camera is so you can hook it up to a TV and display a slideshow on it AFAIK you can't transmit the live feed from the lens, although you may want to check into Czar's post.
I know a lot of those 3-in-1 cheapo Digis can do it.
