Recently BitTorrent has toyed with the idea of switching to a UDP-based transmission method as opposed to the current TCP-based method. The new protocol was designed to combat network congestion, but it almost immediately came under fire with reports claiming it would destroy network traffic. Claims were made that the UDP-based protocol would make P2P traffic more unmanageable than ever, bringing services like VoIP to their knees and rendering networks dead in the water or slowed to a fraction of their normal speed.
In response to these, BitTorrent who created the new protocol has said that such claims are absolute falsehoods. They add that the report is inaccurate in how it describes or interprets their new protocol. To the contrary, BitTorrent says the new protocol will actually make torrent traffic more neutral and fairer, becoming more sensitive to high latency.
In this instance I'm inclined to agree with BitTorrent developers. The report made many generalizations regarding torrent traffic, and makes some pretty bold claims as to what this new protocol will do. I certainly don't foresee VoIP traffic being "destroyed" by torrents.
