I'll respond off the first email because I lost where I was thinking of
responding to.

One git annex repository that I sometimes visit is the
conference_proceedings¹ repository, which has many years worth of
conference videos.  With such a repo you wouldn't actually run `git
annex sync`, you'd `git pull` as desired, run `git annex get
path/to/the/video`, watch the video, and then `git annex drop
path/to/the/video`.  Last I checked there's even tie-in scripts for some
file managers like thunar.

I actually use git-annex with my family's photos and videos, with a full
master copy at my place and one at my parent's place, and a couple of
remotes on the internet.

$ git annex whereis Wedding.iso
whereis Wedding.iso (5 copies)
        00f742bc-02d6-4b05-853a-7703f87b29f9 -- efraim@debian:~/workspace/Flashner_Backup [ct-tor]

        d22b8903-9e94-47f3-8e8a-ef1468e478e3 -- cloud [amazon]
ok

The ISO is encrypted with my GPG key. For this repo I do just run `git
annex sync` because it's really only me interacting with it, and I don't
care about how awful the git history looks.

In our Guix video option, we could upload the actual videos to, say,
archive.org or to audiovideo.gnu.org (or whatever the site is) and then
add the video as a remote `git annex addurl https://path/to/the/video`
and it'll just be available in the repo.
