I was recently interviewed by InfoQ on the topics of Ajax, Comet, Bayeux, RIAs and the Dojo Toolbox.

I was asked to give my definition of Comet in reference to the enough with the connections discussion:

Comet is a collection of techniques, transports, protocols, servers, and clients to deliver low-latency data transit between the server and the client.

The XHR is the least common denominator of Comet, and everything else is an attempt to improve upon the XHR to deliver faster, real-time applications. My definition intentionally avoids some points of the debate, as I prefer to be inclusive and broad, much as Ajax has come to represent everything dynamic in a browser to most people.

I also touch briefly as Bayeux and standards bodies, and JSR-315 for Java Comet servers, and many more general development topics.
