This is a new feature for the 4.0 enterprise version, the Enterprise Network Map:

Is a full featured user editable network map. You can arrange the icons, delete, add new agents, move one or a bunch of them, zoom in/out and set “links” to other maps, just like the classic OVO map tool.

Best of all is all development was done using Javascript and HTML5, so no Java is needed, just a modern browser like Chrome or Firefox 3.x 🙂
