The strength of the federated world will be whether a stream can be best managed through a torture of joins, parts, proxies and handoffs. Then we do it for tv. Start with public access junk, as the free stuff is still better than Reality TV. Show ads if it's feasible and free for viewers then and some money gets back to creators, but allow patrons above a certain amount to avoid the ads by just offsetting the same hosting/kickback cost directly.
