I have been one of admins of a legal but student-operated network in a dorm with about 250 rooms. It was around 2000-2001 and it was 10BASE2 (with BNC connector). It was hell and heaven. On one side we had free, unrestricted couple hundred megabits per second when the rest of the country was dreaming about having a modem. On the other hand there were 5 lines of BNC cable each spanning one entire floor with about 50 rooms connected. Clueless students mishandling their T connector would regularly got significant portion of the dorm without network access. Once had a situation where one of the rooms would regularly be responsible for network disconnections. I binary-searched the spot so I knew it must be inside the room but the room was always closed when this happened and nobody responded. It took some time but I figured it out. The guy had sex with his girlfriend on a bed that rested on the BNC to BNC coupler.
