I have used <a href="http://www.capify.org/ http://www.capify.org/">capistrano</a> to deploy both php and rails applications, it works with merb, and probably camping and rack. You need it check into some sort of SCM, then setup some ssh keys and put in your server settings. Then you can deploy it out. It does take a little getting use to, but it helps greatly once you set it up correctly. It's a build and push to server sort of setup. It's great. On the python front, i wouldn't know, but the newer capistrano seems more open to different types of code-bases. If capistrano doesn't suit you, you can always build up some nice rake tasks that automate it for you. just my thoughts :)
