Microsoft have been listening…it was found that lots of Internet implementations of MOSS were employing an alternative architecture that was not of that intended, due to the license model of MOSS CAL and Internet Sites which could not co-exist on the same web farm. MSFT have adjusted its licensing model over MOSS and it is now allowed. This means that you can now deploy a Internet Site onto a single server for authoring (staging) and presentation, without breaching the license agreement. This would also mean that you would not need to implement Content Deployment and also that content changes, once approved, would be immediately viewable by the public. Tom Rizzo, Director of Product Management, Microsoft has written a post describing this in more detail.
