This is a true story, when I was at uni my pc had a 100mbit NIC and I always got 1-2mb/sec over the uni lan. When I went back in my 2nd year I was one of the first peeps back and my connection was the only one active in all the halls all weekend because I was sad enough to stay in the same room
At the time, on Friday nights you had Alias on, Stargate SG1 and a couple of others tv progs in the US of A and I downloaded them all from streamload Saturday morning at exactly 12.5mb/sec. At the time it blew me away because I had only just come off dialup at home at got VMs 512k bb. Although I am inclined to agree with gavchap in theory, my experience showed me that it is possible. I wish I had a gigabit network card back then just to see what speed I could get off the uni connection.
