is a privacy preserving BitTorrent client that offers permissions for restricting access to shared content and sharing without attribution, with the anonymity being provided by fellow OneSwarm peers routing transfers.
There are several interesting use cases outlined in the author's paper "Privacy-Preserving P2P Data Sharing with OneSwarm" (pdf
