To summarize (in english): to view the site structure 
graphically (with some java applet, for example)

This is rather difficult, due to multiple links (in fact 
the representation is a graph, and a graph is kind of 
difficult to represent..), but the idea seem nice. The only 
thing to make is the algorythm :)
