I don't see anything wrong that should prevent the hard-linking from
happening. If you do an "ls -li" on the source files, do they all show
the same inode number? I'll run some tests, just to make sure that that
the options you cite work for me.

The downsides of that are that (1) you don't get any benefit of skipping
files that are already up-to-date (since it will update the entire
20-gig of data every transfer) and (2) the block size will be pretty
large, so there won't be as much matched data (so more data will have to
be resent over the wire).
