The trend towards a client-rich server-poor paradigm for the web marches onward. KnowNow has open-sourced their asynchronous message routing technology as an apache module. KnowNow has developed software consisting of smart routers on the server and local microservers on the client (simple javascript) to create a system which allows for asynchronous messaging with nothing more than a webbrowser and the ability to perform an http POST. This translates to a publisher/subscriber web application framework which can route messages and events in real time. I remember downloading their developer kit during the Summer last year, but never got a chance to anything more than a cursory investigation of their tools. Matt says to start looking for cool things once developers start building applications that leverage(!) their technology.
