We would need that one blade to be under CentOS Project control (so we could tie down the security tightly ... make it not accessible to the world and only accessable to/from the builder network, etc). But, it sure would be nice to get ppc/ppc64 up to speed as a major supported distro in C5 (and backwards into c4)... and a dedicated builder that we could use would certainly make that much easier. This machine would be ONLY used for building RPMS / SRPMS and the traffic associated getting those files back and forth to the main builder location ... it would not be mirroring any files to other users, so the bandwidth usage would be fairly mild most of the time. Donations anyone :P Thanks, Johnny Hughes
