The BLAG 30k repository has been running for awhile. It has the FC3 errata and many packages from the "mega-merge" repositories. Some of these RPMs are from FC2, but should work fine with FC3. When FC3 packages become available, I'll update.
I have also copied over the *blag* RPMs from 20k to the 30k repository. I will be building FC3 specific ones "in the future". :)
If you are running FC3 and want to enable the BLAG30k repository, put this in /etc/apt/sources.list.d/blag.list
rpm http://www.blagblagblag.org/ 30000/i386 os updates errata
rpm http://www.blagblagblag.org/ 30000/i386 extras
