>They all require two servers running (redis + a web server) So? separating web service access to the datastore is simply separation of concerns and just good modular design. A redis hybrid solution is still going to be faster than Couch. >None provides a framework for building an application. There is lua scripting available in some of them and the application fx is generally on the client. >None provides n-way replication. Out-of-the-box Redis supports trivial (as many as slaves as you want) replication. >None provides offline support. eh? wtf?
