I'd like to start videoconferencing with my partner, associates and friends over the net. First up, I need to buy a decent webcam. I did some research and the two reviews of the Logitech Pro 5000 HERE and HERE seem to indicate that this may be the ideal camera to buy. Perhaps one of you can recommend a better camera that does an exceptional job all-around. My next question concerns actually HOW to communicate over the Internet with these cameras. Will the included software on both MY camera and those of my friends (may have different brands) enable us to mutually connect via a single network? In other words, what service do we use to communicate with each other? Thanks for the advice!
