I've always wanted to write a distributed ArchiveTeam torrent server that, instead of distributing crawlers for ingestion, equally distributed IA torrents to distributed end-user storage (in a VM most likely). If seeding for a torrent dropped below a threshold, that torrent would be advertised to other client nodes to download and then serve themselves. Client VMs could come and go, and the announcer would always ensure remote storage was handled in an orderly fashion.

Perhaps this year is the year!
