Can't we just create a nip for video uploads and have a client aggregate all of the video nips? The client could have some sort of blossom or satellite integration for hosting.
And a (pay per how much you use" type subscription, for censorship resistant nostr youtube doesn't seem like a bad deal.
From my vantage point it doesn't seem like we're too far away, I thought I heard Hazzard speak about assisting or forking flare.pub in the last citadel dispatch episode.
(These are just thoughts from a non dev, plate licking pleb, noob btw).
