Someone mentioned sending the files via HTTP. Is it possible to set up an Apache WebServer with mod_dav (WebDAV) running on it? If your Windows machine has "Web Folders" (see http://support.microsoft.com/default.aspx?scid=kb;EN-US;q195851 ) it might be possible to put the dav directory (and sub-directories) upon the ReiserFS.
WebDAV file size limits: http://www.lyra.org/pipermail/dav-dev/2001-February/001996.html Consider re-compiling apache and mod_dav (or whatever else) with the -D_FILE_OFFSET_BITS=64 and -D_LARGEFILE_SOURCE flags. See: http://www.suse.de/~aj/linux_lfs.html hth, Elizabeth
