Couchbase Lite (http://www.couchbase.com/communities/...) is an ultra-lightweight, reliable, secure JSON database suitable for embedding into mobile and/or desktop apps
It's the successor of TouchDB (http://touchdb.org/) and it does support replication to and from Couchbase. Suggestion is to add it as an integrated plugin and provide continuous updates and support for the Couchbase plugin.
You can easily connect to any Couchbase database that's running in the cloud today via REST APIs.
This is not the proposition as the purpose here, is to have the db on board, ie on the mobile itself.
This is useful, among others things, for offline use.
This mobile db has the capability to sync with couchbase on the backend.
You can try to add plugin couchbaselabs:

Here is an example of how doing it:
