One could also post chunks of videos to a channel on an existing (corporate) video platform in an obscured form, such that they survive transcoding, and reconstitute them in the client. For example, invert the Pr channel, and reverse audio frames (realistically, do something better). There's your free CDN, provided by a legacy video platform in a way which (at least conceivably, if one properly tailors his approach) does not violate their ToS.
