I have a bunch of files I want to track with `git-annex` that are sitting in an external drive. I have a repository sitting on my laptop, but I don't actually have enough free disk space on my laptop to import the files. Really, I just want the file content to be sitting in a special remote. I was thinking the following workflow could be useful:
The proposed `--to=remote` option would add the files to my repo as `import` normally does, but it wouldn't every keep the content in the repo, the only copy would now sit in `s3-remote`. As little disk space as possible would be staged temporarily in `~/my-laptop-repo`. Perhaps the easiest option would be to import a file normally, but them immediately do a `move` to `s3-remote`? But, ideally for larger files, we would want to stream them directly from `/mnt/usb-drive/myfiles` to `s3-remote` without ever staging them at `~/my-laptop-repo`.
