At our university, DC++ was the king. When I started, each dorm room had a 10 Mbit switched port, and each dorm area had a shared 100 Mbit uplink to the university network. So if just 10 people were downloading, you'd instantly overwhelm the uplink. So everyone was instructed to [tag] their username with which dorm they were in, so you'd prioritize people in the same network as yourself for the fastest downloads and so that uni IT could keep a blind eye to us as we weren't killing the uplinks. (a year or two later, the dorms were disconnected from the university network and connected to an open city fiber network with commercial ISPs with 100 Mbit ports and no uplink contention and DC++ went away as people could now use public BitTorrents)
