The project is not ready for general use - and it's a big project.

Not all the repos have a rep (i.e. dag)
Not all packages will be merged (i.e. libdvdcss, adobe-reader)
And the idea, it seems, is to build the packages rather than just copy someone elses. This makes the project bigger.

Thing is - CentOS has quite useable repos of their own; RHEL users should be using up2date or migrating to a non-commercial distro; and fedora users really only have three 3rd-party repos to consider, with all but specialists needing only livna. I'm not sure the project is solving a problem that actually exists.
