Kopete

Kopete is an application designed for KDE that emulates many of the common (and some not so common) internet messenger programs, in particular the following:

• AOL Instant Manager (AIM);
• Gadu-Gadu
• ICQ (part of AOL, also known as QIP in eastern countries);
• Internet Relay Chat (IRC);
• Jabber;
• Lotus Sametime;
• Microsoft Messenger (MSN);
• Novell GroupWise
• Short Message Service (SMS);
• Skype (being removed eventually);
• Winpopup (as issued by a NET SEND command on Microsoft Windows platform);
• Yahoo! Messenger;

The interface is similar to other messenger applications, like that of MSN Messenger or ICQ for example, but has the advantage of hosting multiple accounts using multiple protocols. This means you can have an account with ICQ, MSN and Yahoo! and use a single instance of Kopete to sign into all of them.

Many of the features provided by the genuine messenger protocol are supported by the emulation within Kopete, including the ability to use and receive voice and webcam sessions (though this is largely dependent on the hardware support of the underlying system).
