Griffin, a company that makes a slew of cool mac-related products announced their new super iPod dock dubbed TuneCenter at MacWorld this week. Basically, it's a iPod dock with a S-video, RCA and audio out, some media center type software embedded in the dock, and it includes a remote.
Make Magazine has a shots of the back and front of it on their flickr stream:
Combined with a new video iPod, this small, sleek dock can stream music, photos, and iPod video (very low resolution) to your TV. It's a great idea and clever way to extend an iPod into the living room without a lot of hardware and software. Basically your iPod becomes a rather powerful component in your home theater system, all remote controlled.
I'm surprised that Apple didn't have a product like this in their MacWorld offerings, it'd be great if the Airport Express could have video-out and offer similar capabilities.
