Ctrl-alt-rese is there too. But that's another issue. The content there is often very niche focused. The two big issues are going to be discovery (getting better) and setup.
Unlike a lot of the rest of the fediverse. Video chews through resources fast. So you don't tend to have generally wide open registrations and large content libraries. I've seen a few offering 5GB space with semi open signup. But outside short clips that's going to be useless to well produced content.
I'm thinking of setting up my own at some point. But I'm not exactly the normal kind of person or even the person that tends to produce a lot of content. A lot of those people aren't nearly as techy or into running home servers for fun. I think honestly one of the biggest things for something like peer tube to take off. Is to build up the network of nodes and content. Make it so people can set up a server of their own with just a few clicks on any operating system. Allow for NAT traversal etc.
Then larger fedi operations like World Etc. Could set up something like cache only nodes. Individuals as well. Even with a gigabit connection and a 250 GB hard drive. You could serve many many people. Speeding up access for people in your area.
I think it will all come in time. I mean me installing Slackware on my Pentium in 96 would have never predicted what has happened. And what is happening.
