Kanso Framework. That sounds very interesting - a framework for programming JavaScript CouchApps. So applications that are written in JavaScript and run entirely from a CouchDB installation. The server only needs to provide a CouchDB instance and that's it in terms of requirements - and since CouchDB comes with replication by default, you can easily scale up or implement fault tolerance - simply form a cluster of several CouchDB instances. Equally interesting are replications of the production database to another pot, such as a private developer machine or various other scenarios that are possible with CouchDB. Since the whole thing is based on CommonJS as the language base, JavaScript is not quite as bad as if it were used raw.
