My dorm in 2006 didn't have any wired network (nor wifi).

So what we did is we wired one ourselves through the walls of every room, running ethernet cables from one balcony to the other. Every 6 room, we'd install a cheap fast-ethernet switch.

Eventually, we managed to connect almost all 300 rooms together in a giant single VLAN.

You can still see part of that mess in the history of Google Street View: https://goo.gl/maps/AQriNEJViMELQw8MA

That dorm ended up being a giant eternal LAN party. People would play games all the time, either from their own individual rooms, either after moving their PC using stolen supermarket shopping carts to other rooms for more conviviality.

You'd turn on your PC, and some custom scripts would tell you which games were currently being played, and the only thing left for you was to join the game of your friends, or the game of the total strangers from two floors down.

Fun times!
