the speed of even the healthiest torrents pales in comparison

Again, private trackers. =) I can easily saturate the 2.5Gbps ethernet port on my work PC. Haven't tried pushing the full 10gig link yet, don't want to draw attention to myself since it's only supposed to be 2. It would have no problem though. Private torrents are seeded by seedboxes typically. And torrent longevity on private trackers beats usenet longevity, because some people never stop seeding.
