I am not a Bittorrent expert, I rather studied eDonkey/eMule network.
It seems to me that the ed2k protocol could be used for DDoS attacks,
especially if you set up your own "hostile" server. With 100,000+
clients connected to your server, you just have to add a specific
"ip:port" combination as source for any incoming request.
This kind of attack looks very "promising", for it leaves no track: the
protocol is widely used, and the client is "legit".
I gave a talk on the subject in May, unfortunately it is in French only:

Another possibility would be to advertise someone as a Kazaa or Skype
supernode ... It would require a deep understanding of their proprietary
protocol, though :)
