We do this in our kindergarten class with paper. The teacher checks in with kids who are having big feelings and works with them to identify the feelings on a multisensory activity. I don't think we need a digital mediator here as very young minds often don't differentiate the message from the medium.
Torrents tied to a digital wallet is a clear next step. Creators could get paid and no need for a "distributor". Anyone could host pointers, we could download and pay when we watch.
