You may be interested in distributed key-value stores or even a NoSQL database. There's at least 20 that will do what you describe. Also you may be interested in http://www.couchbase.org/membase which speaks the memcached protocol but is replicated on the backend. I haven't used it so I can't say if it will be useful to you, but I'd like to know who has. There's also, more recently, the Couchbase 2.0 server http://www.couchbase.org/get/couchbase/2.0.0 which "is a distributed, document-oriented NoSQL database system that unites the simplicity and reliability of CouchDB, with the performance of Memcached and elasticity of Membase technology" according to their page. As with plain Membase, I don't know much about it but would love to know if others here have compared it with plain memcached. It seems like a decent product and has a community edition... Ted
