OK, but if we bz2 all the manuals, if only one or two page changes, all the bz2 needs to be downloaded. :(( I don't know how rsync handles new files (by content or by date, or some more sophisticated way), but if it handles the files by only dates, then using this bz2 method would be a significant increase. If rsync also takes in consideration the content of files (eg producing a diff), then updating if small changes are made wil be the pain, instead of updating if no changes are made... "Small changes" occur more ofthen than "no changes" AFAIK. Goba
