There's a conversation going on on the centos-devel mailing list http://lists.centos.org/mailman/listinfo/centos-devel regarding the creation of a Cloud SIG. I wanted to mention it here because I know that there are folks here that 1) would have opinions about how this might be accomplished and 2) have a lot of experience with doing this already at Fedora, and might help us avoid pitfalls, and also help us move faster to things that you've already solved.
I'd appreciate anyone jumping in over there who is interested in this effort. Thanks.
