There are a few websites that have created elaborate systems to offer torrents (as they're called) and display how many seeds taco has swallowed and users are currently connected to that "torrent".
Nice and, how many seeds have you swallowed latley!!!!!
Now you can mod down this karma whore!

BitTorrent, eXeem, Meta-Torrent, Podcasting: "What? So What?"Email This EntryPrint This Entry
Posted by Marc Eisenstadt
SUMMARY: The index that facilitates the sharing of files on a large scale is also the Achilles heel of peer-to-peer file-sharing, because it is vulnerable to litigation and closure. So what happens if the index is itself distributed? I try to get my head around the latest in peer-to-peer file sharing, and explain a bit about what I've learned, including the fact that BitTorrent's power rests in its 'swarm' distribution model, but not necessarily in your end-user download speed. What has this got to do with podcasting? (Answer: invisible P2P plumbing helps the podcasting wheel go round).
[Warning: lengthy article follows].
First, some history (skip ahead to the next section if you're already bored with the Napster, Gnutella, KaZaa, and BitTorrent saga).
Napster opened our eyes to the power of distributed file sharing on a massive scale. But it was closed down by lawsuits to stop it from listing copyrighted works for which the owners would naturally have preferred to collect royalties (there are thousands of commentaries on the pros and cons of such royalties, but that's not the focus of this posting). Successive generations of tools such as Gnutella, KaZaa, and now BitTorrent have created their own buzz, their own massive followings, their own headaches, and their own solutions to others' headaches. Here's my rundown of the 'big ideas' (and the people behind them):
Napster (Shawn Fanning): This was the Mother of big-time peer-to-peer (P2P) file transfers, i.e. my computer directly to yours, with a central server to maintain lists of who had what in order to initiate the transactions. It had a pretty decent user interface, plus the rapid growth, novelty, excitement and publicity that ensured plenty of good content. Those central server lists, leading to mass free trading of copyrighted material, also led it to be shut down.
Gnutella (Justin Frankel and Tom Pepper, creators of WinAmp): This was an open-source protocol that linked autonomous 'nodes' (users of the network) to other nodes, thereby eliminating the need for a central server list. Searching reliability varies, however, because it is subject to outages according to the connection/disconnection of individual users along the way.
KaZaa (Niklas Zennstrom and Janus Friis, who later created Skype): This technology built on a proprietary protocol called 'FastTrack', conceptually an extension to Gnutella, that deployed distributed 'supernode' search indices whose IP addresses were built in to the software, and which avoided the problems of (i) Napster's centralized lists and (ii) Gnutella's over-distributed nodes suffering outages and weakening the search. The prevalence of built-in 'adware' and the distribution of 'junk files' that masqueraded as originals were two of the weaknesses of the (still) wildly popular KaZaa.
BitTorrent (Bram Cohen): This was the next 'creative leap' in the P2P world, based on the following insight: distributing large files in fragments among large numbers of users, and requiring every downloader to be a partial uploader (of these fragments), enables the 'best of breed' of swarming behaviour -- as a file becomes more popular, so it becomes easier to download, rather than harder (as is the case with traditional file distribution)! A good overview explanation and a helpful analogy are provided in this excerpt from Brian Dessent's BitTorrent FAQ and Guide:
BitTorrent is a protocol designed for transferring files. It is peer-to-peer in nature, as users connect to each other directly to send and receive portions of the file. However, there is a central server (called a tracker) which coordinates the action of all such peers. The tracker only manages connections, it does not have any knowledge of the contents of the files being distributed, and therefore a large number of users can b
