 - git-remote-annex - Seems incredibly promising despite issues I've had getting it to install (see below) let alone work quite yet
 
 Also, if anyone is having issue using git-remote-annex, like I did running on OSX installed via homebrew, the solution is to add a symlink manually from (e.g.) `$(realpath /opt/homebrew/bin/git-annex[-shell]) <- /opt/homebrew/bin/git-remote-annex`. In other words, the current homebrew recipe simply doesn't symlink the git-annex command to git-remote-annex on your path, which git annex automagically act like a git remote helper if called like this so luckily it's an easy fix.

+I got this protocol level dump:
+
+	[2024-10-19 16:59:54.229607011] (Annex.ExternalAddonProcess) /home/joey/bin/rclone[1] <-- CHECKPRESENT GITMANIFEST--1eb4e389-9aea-4968-a947-498fd52645e0

+
+That protocol looks fine, problem is parseKeyVariety does not have a parser for the
+GITMANIFEST key type. Once I added that, it got to a different failure that
+looked due to my lack of setup of rclone, presumably it would work with a
+properly setup rclone.
+
+I think this probably affects using any special remote with git-remote-annex.
+This is still a fairly new and not much used feature, and I may not have tested
+it with external special remotes when developing it.
+
+Re your questions, git-remote-annex doesn't care about the details of how
+the special remote is configured, it's up to you to provide an url that
+provides all necessary configuration options for the special remote,
+whatever those are. Spaces in a path should work if properly url-encoded.
