We all know Bittorrent, but we also know it's shortcommings. At first, the exitement was great, as multiple torrent applications were imagined. But the Bittorrent showed it's bottleneck: without a constraint (like on private trackers), people won't bother too much about ratios. But combining ratios with a failsafe monetisation system would only allow new connections to be made to people with better contributions. People wit poor internet connections could pay others with servers in order to get the credit to allow more connections.
I realised that it would be a hard work to program such a system, especially the security part put the payoff would be huge.
