Everybody knows/uses original multistage extension written by Jamis Buck. It works great while you have only one project/app to deploy. It is not quite enough if you have multiple projects to deploy (SOA would be one big use case here). Capistrano-multiproject solves this problem by allowing splitting up deploy.rb into multiple project-specific recipe files.
