ZeroMQ is one layer down the stack. It is higher-level than TCP but it's basically a transport. Bridge comes with RPC and automatic routing. It allows you to expose services simply by instantiating native objects and making method calls. (Like an easier version of Apache Thrift: http://thrift.apache.org/ http://thrift.apache.org/) It also takes care of the socket management and routing for you, so there is no host/port configuration to talk to any endpoint in the system. You can simply address things by a human-readable name like "photo-processor" or "search-server".
