There have been previous attempts at projects such as this. One such project can be found at www.jevans.com (http://www.jevans.com/pubnetmap.html). This project takes data from servers about their connections and draws them in 3D space. The program goes through several iterations where nodes are moved to areas where they are closer to their connections, giving more aorder to the display.
Another project like this one can be found at Mappa.Mundi Magazine (http://mappa.mundi.net/maps/mapps003). This visualization shows the major backbone servers of the internet and their connections. The servers are located on a 3D globe where they are located in real life. This gives the viewer an idea of what regions are the most "wired", or connected to the internet.
A link from this site goes to CAIDA (http://www.caida.org). This project uses a 2D representation of the earth to place servers geographically and then shows connections through the core of the earth.
