> The particularities of CouchDB replication are very well suited to a enterprise application with a distributed architecture that I'm working on.

That is what made it stand out for us. CouchDB carved itself a nice niche in that area and currently doesn't have any viable competitors. We have a cluster that runs continuous replications to sync data around and it works great. Had we used Erlang we would have used Mnesia (the dataset and pattern of access fits it well) but we use Python & C so CouchDB works great for us.

Also wondering what future will bring and if they'll ever end up with some hybrid of Membase+Couchbase? Reliable document saving and replication + fast key value store, rolled all in one?
