How about something with rsync and inotify? A program could use inotify to watch for changes, queue up the changed files and call rsync on the files in the queue. If a file is changed more than once before being copied the first time, the other entries in the queue could be skipped. -- Michael Wood <esiotrot(a)gmail.com> -- John M.
