I'm at the CouchConf -- the demo of UnQL was fantastic.
The idea is that you shouldn't be locked into a NoSQL database, and that one language that would work across all NoSQL databases will grow the community. How each database manages their implementation of the spec is up to them.
INSERT into c1 value {"foo":1, "bar", ["a","b","c"]};
Now ignore the datastore behind that-- it could be Mongo, Couch, etc etc, but you know that your query won't need to be rewritten in case you decide to switch databases. This can only be a good thing.
