There are many cryptographically secure methods currently in testing and development that can create a high security anonymous network for data publishing, i2p is one such network, and the other is the EFF sponsored Onion Skin Router
(cache) network, or TOR. If you want to use Bit torrent with TOR, check out the wiki article Anonymous Bittorrent with TOR.
You should also check our Anonymous P2P and Anonymous Bittorrent pages periodically as we add new guides, downloads and materials.
