White Paper from Sun on Virtual Worlds that basically gets it right. "Today's virtual worlds represent the first phase of 3D Web. Dedicated servers running their own virtual worlds are to 3D Web what MySpace is to today's Web. In the future, 3D Web will be a network of virtual worlds that are owned by various entities. The success of virtual worlds will depend on factors such as openness, enterprise-strength platforms, vibrant communities, and a portfolio of services." Via Pacific Rim Exchange.
