I have been working on a way to collect network data and create node maps of the network (entire network, not just 7 hops), and it is almost finished, so i thought i would post and see what everyone thought.
The link is

Has been working great so far, and I just release the application.
I wish it was compatable with limewire, but currently it is not. This is a great way of collecting data, and I wish every client would post the same information that gnucleus did.
Anyway, just thought i would bring it to your attention, see what everyone thought. I would be very interested to hear the developers opinion.
