Have you tried talking to universities or university video providers (e.g. Echo360)?

A lot of universities are part of networks (e.g., the one I teach at, UNE in Australia, is part of the Regional Universities Network.) So they seem to fit the pattern of organisations that produce and host a lot of videos (course videos), don't like YouTube (we sometimes get told off for putting course videos there) and are part of networks that might like federated access to each others' video collections (while we mostly produce our own - it's not tv it's a teaching course and students usually want to hear from their teachers - sometimes we'll want to include something like a guest talk from industry).

Universities may be less interested in the bittorrent streaming aspect (they already successfully stream video and don't face the ridiculous peaks in demand because most videos aren't public) but ActivityPub to be able to search selected videos from each others' repositories could be interesting.
