I Need a program to connect to the various p2p networks and gather stats on active users and

puts them in a database, the end result being a page like this:

http://www.slyck.com/stats.php

We are running a Fedora system so we would prefer the program to be written in C or a

comparable language.

I would like to interface with these networks:

eDonkey (emule)
FastTrack (kazaa)
Gnutella (limewire, bearshare, etc)
Overnet
Filetopia

The top three are the most important. I would like to connect to all these networks, get a

count on # of users, and as much data as is available.
