Actually, it's better to send the documents and NOT hold up to a tv 
screen for LOTS of clear communication reasons.

But also, HD is NOT needed for adequate and even quality 
videoconferencing. I laughed when I heard that idiot Phil Burgess 
from Telstra with the big mouth last week say you need 45mb for 
videoconferencing. Rubbish! You need that for broadcast quality 
equivalent television. Videoconferencing is NOT broadcast television. 
128kb is adequate, but 512kb is fine. The trashy videoconferences 
people experience has nothing to do with bandwidth, but IS due to 
poor room equipment configuration, the worst being lack of proper 
microphone placement. I've done that many vc projects that I know 
where the bad decisions are, and that is always it. If you can't 
hear, you can't communicate, even if you have an HD picture.

But you do need symmetric traffic for equitable participation, 
something that is lacking in most DSL subscriptions although available.
