DKMessenger is a free Peer-to-Peer communications system with video, audio, text chat, file transfer and much, much more. If you have a microphone and a camera hooked up to your PC, DKMessenger works as a free videophone. If no microphone is available, the conversational aspect of the program can be accomplished through text-to-speech (TTS) synthesis, which speaks the text of messages typed by your buddies. All this happens in real time and conversations occur as fast as you type. DKMessenger supports application sharing; let your buddies see any application running on your desktop. Also, on the whiteboard, just click the Board button and everyone can share images and text.

Version 3.1.7 enables offline use, which permits direct peer-to-peer access with having to logon to the DKMessenger server.
