Jean-Francois Arcand, of Grizzly fame, says it best :
"Introducing Atmosphere, a new framework for building portable Comet based applications. Yes, portable, which means it can run on Tomcat, Jetty, Grizzly/GlassFish or any web server that support Servlet 2.5 ... and without the needs to learn all those private API floating around..."
The existing Comet (also known as Ajax Push) landscape is both promising and in need for some standardization. Even with the Servlet 3.0 (JSR 315) working on standardizing Comet, Project Atmosphere promises a layer of abstraction today and alignment with the standard tomorrow.
