Simple JavaScript Applications with CouchDB - CouchApp.org. Interesting approach: entire applications are implemented in HTML+CSS+JavaScript and stored directly in the CouchDB, also persist their data in the CouchDB. Reminds me a bit of Frontier, only here CouchDB and JavaScript are used instead of the Frontier Roots and UserScript. The big advantage: if the application actually gets by with the elements used, you get the easy scalability so to speak for free - because CouchDB can be easily scaled by starting multiple instances. Maybe it becomes clearer what it means in this tutorial.
