This is a peer-to-peer communications system with video, audio, text chat and file transfer.
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 synthesis, which speaks the text of messages typed by your contacts. All this happens in real time and conversations occur as fast as you type. DKMessenger also supports application sharing. Also, on the whiteboard, just click the Board button and everyone can share images and text. Includes message font and formatting support.
