Chainsaw is designed as a web service for hosting real time event streams in a variety of situations.

Built on other projects of mine like Spinderella and my rewritten version of jssocket, it is a simple web service that manages both the persistence of event streams and the live updating aspect.

More importantly, it was built so application developers can embed a single js file in their application (to subscribe to event streams) and adding events is a simple HTTP Post – meaning you can easily (and in mere minutes) add real time event stream support to almost any web application.

I also have a hosted version of the service in the words, pending a rewrite of the javascript.
