I would say there are still 2 options how to build "add-on" packages
that install/run on top of Fedora and it depends whether they create
dependency chains or are standalone.
For standalone packages (= their Buildrequires can be resolved solely
from the Fedora repos) one can use scratch builds koji and grab the
results (= rpms) when the build finishes.
For packages with dependency chains is using an own "builder" machine
required. The mock tool is capable of managing a repo with built rpms,
so it shouldn't be difficult to achieve on our public guest.
