Currently only really accessible via the API. The UriAdapter creates a tempfile from a url and gives a ActionDispatch::HTTP::UploadedFile back to the controller to process as normal. This will help a lot in being able to transfer avatar urls from another app without monkey patching a lot of discourse code.
