Famous and very popular media search engine, The Pirate Bay, perpetually in the crosshairs of Big Media to shut it down, is to shift away from torrent files from next month and replace them with Distributed Hash Table (DHT) and Peer Exchange (PEX) technology reports ExtremeTech. They have actually been using these for quite a while now, as this is the technology underlying their Magnet links which have appeared next to the torrent links as an alternative way to download. They have done this, because torrent files are stored centrally on a web server, which makes them vulnerable to aggressive rights holders who want to take them down, while Magnet links are decentralized "trackerless", removing this vulnerability. Also, at the moment, it's impossible for anti-piracy outfits to tell how many files a user is sharing when using Magnet links, or what they are. From next month therefore, only Magnet links will be available. Note that Magnet links are compatible with various anonymizing services, for anonymous downloading, but there can be a significant performance impact on those services. In fact, TPB has been using Magnet links with torrents for some now too, but just did so quietly, without telling anyone.

Popular BitTorrent clients such as uTorrent already use Magnet links as easily as torrent files, so there won't be much difference to the user experience. The main difference, is that they can take a bit longer to get going, but the final download speed isn't any less, due to the cascading exponential pyramid nature of incoming peer connections guaranteed to max out any internet connection, when there are enough peers.

Well, it looks like the freemium model of selling software is working quite well in the industry, as Bram Cohen's very popular BitTorrent application, uTorrent, has just adopted this model. Known for being fast, efficient and light on system resources, it has now gained a few pounds, sorry features in version 3, some of which are available only for a subscription of $24.95 per year. These include things like an antivirus scanner powered by BitDefender, a media player and integrated support for converting popular video file types such as MPEG4, H.264, Theora, and VP8, as well as MP3, AAC and AC-3 audio files. The media player is interesting, in that it allows playback of videos that are still downloading. Note that this feature is also available in the free version.

For those that still want to hang on to the lean and mean free version, it's still available and isn't going away any time soon. Both versions can be compared here. Perhaps it's ironic that this legal application which is often used for software "piracy" can now itself be pirated… Cohen's take on this will be interesting.
