Well, instead of me getting information out of JavaOne.. someone sent information to Slashgeo instead.  but anyway, one of the many things that is coming out of JavaOne is Knowledge Planet's use of WWJava.  Knowledge planet allows the visualizing of massive amounts of textual data on a virtual globe.

At the time of map generation, the planet’s topology is determined by the content of the knowledge base. The peaks of the virtual landscape indicate abundant coverage on a particular topic, whereas valleys represent sparsely populated parts of the information space.

You can try the Knowledge Planet demo here.
