An opscode hosted CI for community cookbooks

With growing number of community cookbooks and available testing frameworks for chef, it will be helpful if the community cookbooks go through a CI (something like travis) where the cookbooks are tested against their supported operating systems. The end result should be the build status for individual cookbooks available in the community site along side their version compatibly with their dependent cookbooks (something that gemnasium provides for ruby gems). It will greatly facilitate development of portable less buggy cookbooks available in community.
