A user could have the distribution source on a CDROM and view it via a cache file server. This would store only the files that have changed - using copy on write. I suspose this could be extended to storing only the blocks that have changed, or even file diff(1) output, or wrap(8) file even... I'am not sure if this is interesting or hedious :-) -Steve
