I would say that a great many things are not noticed by or are tolerated by the majority, and it's only when they're presented with a better solution do they notice. Even client-server business models can benefit from peer-to-peer communications. The most obvious is media providers using their clients' connections to avoid having to maintain as large a CDN, and to cut some costs that way. If someone's listened or watched something near you, you can download from them instead. And then there's all sorts of systems which really could be truly peer-to-peer, from social networking to a replacement for ebay.
