I have used Skype for a number of years now and find it great for voice or video chat accross the net. Skype is currently going through the beta stage of its next version. They have just released beta 3. I have been testing it and so far it works well. If you are familiar with Skype you will find that the new version has alot of changes to the interface. I have taken a screen shot I have of course blurred out some private information from my contact list.
