for a while I thought I might go to one of those uniquely nerdy colleges where they let you fuck around with dorm infrastructure.

i back-of-napkin'd a whole packet-over-laser relay system based conceptually on the clacks that'd give every room/station its own serial-interfacible (up|down) link. you could link buildings out of windows and stuff. horribly impractical and prohibitively expensive, but the kind of thing that could only happen in a university on-campus environment.
