BearShare, built on the Gnutella protocol, is designed to let you quickly and easily share files with everyone on the Internet, and download files that other people are sharing. It works with all types of files, and allows you to search for files that contain specific words or phrases.

The KaZaA Media Desktop is a second-generation peer-to-peer file-sharing service with which you can search and download media files from other KaZaA users. You can also organize, view, and play your media files through an integrated media jukebox, publish your own work, reach an audience, and communicate with other KaZaA users. KaZaA supports audio, video, images, documents, and other file formats. It features recommendations and an automated feature that lets people communicate with contacts.

LimeWire's elegant user interface is like no other Gnutella application available. LimeWire is capable of multiple searches, available in several different languages, and is most famous for its ease-of-use and cross compatibility. Limewire is written in Java, and will run on Windows, Macintosh, Linux, Sun, and other computing platforms.

This latest version of Morpheus gives prior users a compelling reason to give it another try, after the turbulence of this last year. When Morpheus first moved to the Gnutella network, it didn't live up to the quality that made its earlier reputation. But this new version announces its reformation with a colorful Superman-style "M" logo; and the style changes go way deeper than the logo. The overall interface looks great. It's well laid out, offering tabs for search, traffic, and media management. The buttons are big and, though they won't win any cool awards, easy to use.
