Hmm yea, though running on window mode has been used for ages and isn't bad. It also helps that you have a good quality webcam to fill the screen without it going all pixilly.
Any broadband connection (maybe 256 summit, or 512kb) i think would be fine for it. Though of course, faster ones are welcomed.
