Agreed that it is too late to enable DeltaRPM by default in Fedora 7. 
However, the yum plugin will be available in the distro as an optional 
add-on.

We should begin discussion of things like:
- standardize a future directory structure and location for deltarpms 
within the new mirror format.
- where and how deltarpms are generated to land on the master mirror.
- Are we satisfied with the existing metadata format for deltarpm?

After we have settled on standards for all this, then we can add 
production deltarpm to the mirrors for Fedora 7 users to optionally use. 
  Perhaps by Fedora 8 we can enable the plugin by default.
