Textbased MSN Client

TMSNC (from Textbased MSN Client) is a textbased (console) client for the MSN Messenger protocol. It works on Linux, MacOS and BSD systems. The goal of this project is to create a client like MSN Messenger (with sound, webcam and file transfer support), but without any graphical features. The current version of this messenger is 0.3.2. You can download Textbased MSN Client here.

KMess - Open Source Messenger for Linux

KMess (current version: 1.5-pre2) is an open source chat client for Linux which allows you to chat with your friends who are using MSN Messenger. It focuses on the specific features of MSN.

Some of the main features of KMess are:

• Support for group chats with multiple contacts.
• Picture and file transfers.
• Emoticons and text formatting are supported.
• Chat logging.

You can read more about its features here and download it here.

ooVoo - Video Messenger

ooVoo is a free application which you can use to talk face-to-face with your friends with high quality video and audio. Using ooVoo you are able to:

• Include up to five people in your conversation.
• Send video messages to a specific person or a group of them.
• Of course, text messages and file transfers are possible.

The application has a nice 3d video interface which is convenient and intuitive and nicely compliments the Vista style. All you need is a webcam and a headset (or separate microphone and speakers, of course). The installation takes up to 20 MB.

It seems that ooVoo is trying to be a competitor of Skype. Unfortunately, with ooVoo you cannot call out to standard phones. However there is click-to-call, and the ability to send video messages to non-ooVoo users. The quality of the video and the sound is definitely noticeable.

The ooVoo instant messenger is definitely a very interesting and useful application. One of the biggest problems would be to convince your contacts to switch to ooVoo.

I've found here an interesting story of two people who married using the ooVoo messenger. I don't know if it's real but it sounds like a funny and exciting story.
