    Skype has recently see the start of some intersting plugin for it, especially for adding Video to it

    • vSkype www.vskype.com adds video and sharing to your Skype experience. Getting started is simple. Just connect a camera, and invite up to 200 buddies to a video call. It does not exist right now but may appear soon.
    • Dialcom's Spontania www.video4skype.com video plug-in is designed to be integrated with any 3rd party Internet-based communication solution. It is right now available for skype (windows only :-( ) and it work perfectly.

    In order to enjoy video with a computer, I recommend You to buy a GOOD webcam: (sorry to say that I did not have any luck with 2 basic logitech webcam at 60 euro). Buy at least: 640x480 pixels at 60fps (120euro), nothing else! Philips webcam are known to wook good in low lights conditions. it's a more expensive combo but You will never regret it!
