> CouchDB is a document database that supports two-way replication so you can re-sync after taking part of the data offline, but it's still designed around the concept of a single master that holds all the data
To clarify, CouchDB's replication features are peer-based and ad-hoc, there is no "master" replica. And you can take part or all of the data offline, or spread it geographically.
I think by single master, you mean CouchDB doesn't have support for partitioning a single logical database across machines, which is true (though there are projects for large scale partitioning with CouchDB, but it's not in the core yet).
