Kazaa's revamped it's value proposition: it's Kapsules let content owners package whatever they want, and offer them via the P2P network to consumers.
According to Kazaa, this has two advantages. First, it cuts bandwidth costs for producers. Second, it lets content owners control their content, and distribute more than simply songs, or games - they can, for instance, offer a Kapsule of lyrics, songs, videos, etc.
Is this compelling? It certainly does offer both producers and consumers benefits. The bandwidth costs are a little less important, I think. The Kapsules idea is cool - and that's what's important: this market needs risk-takers. Eventually, someone will unlock consumers wallets - but it ain't gonna happen without experimentation like this.
