I'm not so familiar with ediff, therefore I don't know, whether this can be changed easily, running the diff command on the remote host. However, this introduces more complexity into ediff: there might be protocols which do not support execution of remote commands (like ftp or smb). Furthermore, ediff would need to check, whether the files to be compared reside on the same remote host. I don't believe that this shall be changed before the release of Emacs 23.1. After the release, it might be a new feature somebody (with more skills than I have on ediff) might implement. For larger files, I recommend to use the scp method instead of ssh. Best regards, Michael.
