This was the idea with SPK Network. People, community members, could host videos themselves, thus making them live forever. They would get bootstrapped, if you will, to 3speak's infra, and thus delivered out that way.

As far as I know SPK network is abandonware at this point. Disregard wanted 300k to finish it, because GPT told him to, or something like that. Anyways, not trying to bring up drama.

Right now the plan is to store people's videos, no real expiration date. This can change, it probably will, but no signs of that happening any time soon. Unless the app goes viral and 3speak runs out of HD space. That's another story altogether.
