Thanks Sean, that makes sense. I've just now read another message by Luciano Ramalho, where Luciano essentially writes the same in the paper at http://journal.code4lib.org/articles/4893 CouchDB was influenced by Lotus Notes, a networked, collaborative application suite designed to support users who are often off-line. So, CouchDB allows master-master replication, that is, synchronization between peer nodes which have received inserts and updates independently. MongoDB supports only master-slave replication: only one node receives updates and inserts, and replicates to the slaves. - Nebu
