Sun's open source 3D World, and 3D web as a training tool for WMD management

A couple interesting links, first is Sun's project Wonderland, open source client and server for their 3D world. This looks like it's in early stages of development, but you can run the client and the server on your own, always a plus!.

The vision for this multi-user virtual environment is to provide an environment that is robust enough in terms of security, scalability, reliability, and functionality that organizations can rely on it as a place to conduct real business. Organizations should be able to use Wonderland to create a virtual presence to better communicate with customers, partners, and employees.

Second, Idaho Bioterrorism Awareness and Preparedness Program, using 3D web (in this case Second Life) for incident management training...

This virtual environment spreads over two islands Asterix and Obelix (65536 x 2 sq. meters), with one island dedicated to a virtual town and the other a virtual hospital. The design of this virtual environment is influenced by dioramas frequently used by emergency services to support their tabletop exercises.
