alt Hacker NewsDoesn't really answer the question though, why would someone be trying to utilize that much bandwidth out of their house?
Is this for people trying to start the next netflix out of their garage before they have any money to put the servers in a colo?
VPNs. If you have a NAS and require high-speed access from/to your home files (dumping your Apple ProRes RAW rushes off your external SSD, so you can keep shooting your video, for instance), that kind of bandwidth cements your income.
