Another approach would be to let the swarm nominate videos to include in the bundle. Whenever a new stream is added, others in the stream are notified of its inclusion, they can check out that new stream, if they think it is relevant to the original stream, they can start bundling it in as well. As more nodes broadcast the same new stream, it rises in the ranking of nominated streams for inclusion. Once a quorum of swarm nodes thinks a stream should be bundled it is added. Of course other users can specifically avoid certain streams if they think it is spam or if they have limited bandwidth to share.

This approach would basically work like a "decentralized" video subreddit. i.e. an "ephemeral" social network with accompanying live video.

Streaming of live comments/chat over torrents would also be fascinating.
