Create a content distribution system, which will enable a person to send a video stream (i.e. animu) to a large number of viewers, while not consuming as much bandwidth as unicast would. The system should construct a scalable multicast network; you can assume that the upstream bandwidth of each node is at least as large as the stream's bitrate. The solution should use digital signing so that a malicious node couldn't fake the stream. Deadline: Saturday 2:00AM (Japan time).
