Useful for moving large amounts of data without having to worry about bandwidth and paying a middleman(webhost). This could extend to sending resources to team members or online distribution of full games and/or demos. The more you give(upload to others), the faster you can take(download to your PC), so no one has an advantage and no more crashed servers and headaches.
