How it works
Yum Presto plugin uses deltarpms aka drpms which are binary diff's
between updates and the original version. So if for example
Openoffice.org gets a update that changes 3 files the delta rpms would
contain that instead of the full update which is essentially a complete
new installation of the package with the configuration files preserved
from the older version.

# yum install yum-presto (plugin is in Fedora Extras)
Edit /etc/yum/pluginconf.d/presto.conf and enable the repositories. Do
not enable development unless you are using the test/development version
of Fedora. Core and Extras repositories are available in the
configuration file and commented out.
Livna is also available at http://www.lesbg.com/jdieter/
# yum update
You should be able to see presto plugin being loaded and delta rpms
being downloaded instead of the full updates along with whatever size
savings that gets you post installation.
