a Facebook Fan Page for any site on the web?

OpenGraph is coming. "Ethan Beard, laid out the Open Graph as essentially a Facebook Fan Page for any site on the web. So you can imagine that you might be able to create a Facebook-style Wall to include on your site, but able to update your statuses from your site, leave comments, like items, etc. Again, it’s like a Facebook Page, but it would be on your site. And you can only include elements you want, and leave out others."
