First thing comes to mind is CouchDB should not be general purpose HTTP server. You will agree that you can't create real time chat in under 100 lines of Ruby code alone (still you need javascript) This chat application author coded application in 100 lines of Javascript including validation that run on server. I can clearly see the benefits of approach CouchDB took with CouchApps. I also know its not answer to all needs of Webapps.
