I'd love to use iChat, enough users with iSights around, nice interface etc, just too bad that my corporate firewall doesn't allow me to do more than plain text chats, and guess what they won't open the ports necessary for videochat. So great idea but lets talk again in 2-5 years when the corporations begin to see the benefits of videochats/ videoconferencing without dedicated equipment.
Alternatively could someone please tell me a way to use iChat without all those nifty ports opened, you'll get a beer and my eternal thanks
