The other thing to consider i that with such a large differential between 
upstream and downstream bandwidth, you may, if downloading several things 
at once, come up against the problem that your upstream bandwidth iss 
insufficient to cope with all the ackn packets you're having to send, thus 
throttling your download peed.  You can help this problem by using the 
traffic shaper.  Thi is a common problem with high-speed adsl lines.
