He's not talking about video-conferencing with a dinky webcam which yes, has failed. He's talking about a system where it really feels like the person is there. The attributes of life size-ness (sp) and eye contact make the difference. I don't think people will want this to replace telephone calls, rather to hold business meetings. A Thanksgiving dinner would be pretty cool too. So it feels like everyone is at the same table.
