One caution: If one is managing multiple pc's with redundant files across them
(e.g., OS, apps), then you will waste a lot of bandwidth (and time)
copying them since you will lose the pooling. Alternatively, if you
use rsync with the -H flag, then you are back to the problem of rsync
choking on hardlinks.
