Notes

Template:Fnb BitTorrent Open Source License is not considered free by Debian Free Software Guidelines, see [1]
Template:Fnb Automatically configure port forwarding (requires UPnP-capable OS & Router with UPnP support)
Template:Fnb It allows you to use trackerless torrents or (with some clients) to resume normal torrents when their tracker is down
Template:Fnb Is not compatible with the official BitTorrent DHT support.
Template:Fnb Tracker included with Linux binaries and with source, but not with Windows binary
Template:Fnb Recently implemented (unofficial) web seeding feature, see HTTP-Based Seeding Specification
Template:Fnb Currently this program is no longer offered, or supported. See authors website: http://www.torrentstorm.com/
Template:Fnb You can select which files to download when using the gui client, but not with the curses (text) client.
Template:Fnb Used to contain both Adware and Spyware, non-"Pro" version continues to contain Adware. *New note* Latest versions (1.4.3+) of eDonkey ALL contain adware, which can NOT be opted out of, even with a "Pro" install. Use an older client version or stay away!
Template:Fnb Provides a java-based and a simple HTML/JS based WebUI
Template:Fnb It's not a DHT network, but Shareaza uses gnutella2 to find other Shareaza clients when the tracker is down
