I am developing an open "protocol" for dynamic ridesharing services using mobile phones. It is based on XML-RPC and uses marshalled objects as parameters (quite like Soap). Every entity and operation will be heavily documented in the draft. As example, look at this first skeleton of a documented Prefs object to be used in the Protocol....

I have created a protocol in Clojure 1.2 that handles my own Java classes and has default handling for a generic java.lang.Object.

Hello, I'm giving a presentation to some undergraduates & post graduates (as part of their computer networks course) on real world client server communication. "real world" is the key here. So, I want pick 4-5 case studies of popular real world client-server communication protocols that may help them in future. So far, I've thought of...
