I'm not arguing anything about P2P efficiency. Whether or not it's comparatively efficient, counter to a particular network design, or even "fair" to the ISP, it is the case that its use is growing. In a competitive market, those ISPs who update their networks to accommodate the growing appetites of their users (just as is happening in every other industrialized country) stand to gain a competitive advantage.
