Here we provide two examples of OODSS in action. History Echo is a basic example of how to setup a client and server, making requests from the client and responding from the server. This example will help you get a feel for how we use s.im.pl serialization, to define the messages that comprise a service, and how to use client connection scopes to maintain session-private state. Next, the public chat tutorial showcases a new functionality: the ability to send asynchronous updates from the server to the client.
