Well, there you go! A gadget-ethernet connection is an excellent idea that would likely be useful to many that desire only to push files around and/or modify their contents rather than mounting as a mass-storage device (which is what I assume is happening currently). I believe SSHFS and SFTP do not require a network connection, merely a data stream, so even if it wasn't ethernet, an ultra-simple protocol could be devised for this operation via USB (perhaps one already exists?).
