Re: [p2pi] Real life torrent statistics

Stas,

Thanks for the valuable information. I think if we can collect the
connection information between peers, and draw a map with the information of
distribution of the peers and their connections, then it will be of great
help. However, perhaps the connection information may not be collected from
the tracker.

Best Regards,
