If CentOS is to start building presto-enabled repositories, here's what
needs to be done:

   a. deltarpm & yum-presto added to CentOS repositories
   b. CentOS build system modified to generate deltarpms.

As for how to do "b", that depends on what CentOS is using for their
build system.  At Fedora, the plan is to have koji generate the
deltarpms, but I'm not sure if you're using koji.  If not, CentOS would
need to go down a separate route.

When it comes to problems, the plugin is designed to fall back to yum
downloading the full rpms if there are any.
