Well, if you are moving things around, you can use rsync's '-H' flag... 
as long as all the files that are the same are in the transfer, rsync
will see that they are the same and hardlink them on the final dest. 

There is also a 'hardlink' command that RedHat/Fedora have been using
on mirrors for a long long time. If you are using RedHat/Fedora you can
just 'yum install hardlink', otherwise you can pull it from cvs at: 
http://cvs.fedora.redhat.com/viewcvs/devel/hardlink/
