eXeem Beta 0.16 Screenshot

eXeem was a peer-to-peer (P2P) file sharing client using the BitTorrent protocol. eXeem was designed to replace the need for centralised trackers (servers which co-ordinate the transfer of metadata across a BitTorrent network). It largely failed to achieve this goal, and the project was canceled and eXeem's network was shut down by the end of 2005. eXeem Beta . ... eXeem Beta . ...

Criticism of eXeem

Criticism of eXeem arose soon after it debuted and included:

• eXeem's for-profit operating model, including support through advertising (much akin to Kazaa) and a public beta that included HTML ads supported by Cydoor, which is widely considered to be spyware ^[1]. Ads-free versions called eXeem Lite[1] and BIT eXeem were subsequently released, and eXeem later replaced Cydoor with WhenU from version 0.21 onward.
• Closed source code development, in contrast with the open source model followed by the most popular BitTorrent software, on which eXeem is based.
• No initial Linux or Macintosh versions, with no ability to allow third parties to port the code beyond Windows (as eXeem is closed source).

Network

The eXeem network used super-peers that were used to track torrents (as ordinary bittorrent trackers). These super-peers were also responsible for maintaining file lists, comments and ratings for part of the files in the network. When a peer that was tracking a torrent was closed or went down, a new peer was assigned to be the tracker for that particular torrent.
