Zur Bedeutung, eigentliche Motivation, deshalb damit beschäftigen
A new Internet traffic trends report released by the Canadian broadband management company Sandvine reveals that global P2P traffic is expanding, with BitTorrent as the key player!. In North America, more than half of all upstream! traffic (53.3%) on an average day can be attributed to P2P. The report further signals some really interesting regional differences in P2P use, such as the dominance of Ares in Latin America.

Nach Start sind nur erreichbare Peers nützliche Peers
Später nicht-erreichbare Peers incoming, wenn selbst erreichbar

Zusicherung der Anbieter, sicher durch Ausland
Anonyme Bezahlung?
Wait, what?
Lieber nur Torrent-Traffic, Isolation bspw. über Virtualisierung
