+Thank you, `remote.foo.annex-readonly` looks like a nice solution for the update-changes-from-other.sh!
+
+For discard-all-my-changes.sh, `reset --hard` through proxy worked otherwise nicely, but it doesn't seem to restore deletions:
+
+    $ git annex proxy -- git reset --hard origin/master
+    HEAD is now at 37aed97 git-annex automatic sync
+
+    $ echo \"A\" > test.txt
+    
+    $ git annex add test.txt
+    add test.txt ok
+    (Recording state in git...)
+    
+    $ git annex sync
+    commit  ok
+    pull origin
+    ok
+    push origin
