-I think this would work as a faster alternative to --clean-duplicates,
-using a directory special remote:
+Using `git-annex import --from remote --fast`, when there's a huge file in
+the directory remote, will hash it, but only once. On subsequent runs it
+will recognise the file it has seen before.
+
+So all that's needed to emulate --clean-duplicates is a way to do this:
 
-	git-annex import --from remote --fast
 	git-annex move --from remote --copies 2

+Which doesn't work currently, but see [[drop_from_export_remote]].

+git-annex could just alter the tree exported to the remote to remove the file.
+It might be a little slow to do that for a lot of files, and it would create
+some unattached tree objects that would linger until gc. 
+
+A simple optimisation would be to remove the file (with removeExport) but not update the
+export tree for one file. Keep a log of removed files, and at the end of the command,
+or some future point where the export tree is used, update the export tree to remove the
+files from it.
+
+This seems like a prerequisite for [[remove_legacy_import_directory_interface]] because
+`git-annex import --deduplicate` and `--clean-duplicates` need to remove individual files
+from the remote.

 One approach would be to make the old interface be implemented using the
 new interface, and paper over the cracks, by eg setting up a directory
 special remote automatically.
