The git-clone manpage says you can use the rsync protocol for the url.  
If you use rsync:// as your url for your remote does that get you the 
rsync delta-transfer algorithm efficiency for the network bandwidth 
utilization part (as opposed to the on-disk representation part)?  (I'm 
new to rsync.)
