was a peer-to-peer
(P2P) file sharing client
using the BitTorrent protocol
. eXeem was designed to replace the need for centralized
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 was written in C++ using the open source libtorrent library for its bittorrent functionality.
eXeem was created by Swarm Systems Inc.
which is located in Saint Kitts and Nevis
. The company employed Andrej Preston
, the founder of Suprnova.org
, as its spokesperson
and public face of eXeem. Five thousand Suprnova.org users were selected to take part in a private beta test
of eXeem before the public beta was released on January 21
eXeem's developers expected to implement the following features:
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 . Ads-free versions called eXeem Lite 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).
- Seacay was released as a Linux Client for the eXeem network when eXeem version 0.21 was released (see screenshot, right )
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.
