Not entirely related since this is less of a peer-to-peer and more of a "how do we solve things like paying for website views", but I really liked Rivest's approach for "Electronic Lottery Tickets as Micropayments"[1], as it keeps the amount transacted high enough to avoid transaction costs being a material amount, while also meaning that customers aren't charged that much for any individual transaction.
