Unison ( http://www.cis.upenn.edu/~bcpierce/unison/ ) is a stateful
two-way synchronizer that does essentially this by default; you can
use Unison even for your one-way copy to get the performance benefit.
Rsync is meant to be stateless, so if it were enhanced to reduce the
amount of file list transferred, I think delta-transferring the file
list would be more in keeping with its mission than saving a "last"
