Docker should help in general with making services like this more accessible. I can imagine someone like Fastmail using docker to allow a one click process to set up a Diaspora or Mastodon node. That should take the hassle out of it, and if you could just watch a 3 min video to explain the concept/metaphors, and set it up in 30 seconds, it expands the possible audience from system admins and software engineers, up to anyone technically inclined.
