Bittorrent does not need to be protected against NSA, but for it to provide some cover traffic the settings should also not be too damn de-anonymized. Put plainly, in I2P, warzing, seeding, copying movies et.c., increases your anonymity. (if you do not de-anonymize it too hard, ie. maybe use at least 2-hop tunnels?) Depending on how paranoid you are, you can change those settings in I2P, and these settings can be made per application (e.g. web browsing, bittorrent, IRC, ...).
