As far as I know folks should be able to continue to use the Cloudant project with CouchDB until it's merged. I personally haven't used it recently, but do work with CouchDB regularly.

Looking at the big picture though, the main project is committed to this direction, so it's definitely worth spending the time if interested in DynamoDB-style clustering (or clustering in general) in CouchDB.
