I think there's some terminology confusion. "comet" *is* widely supported,
as it involves long-held HTTP requests via streaming or Ajax long-polling
(see http://en.wikipedia.org/wiki/Comet_(programming)). Technically,
comet_messaging.py isn't really "comet", but instead uses the newer
WebSockets protocol (see http://en.wikipedia.org/wiki/WebSockets), which is
not yet widely supported by browsers.
Here's a three-part blog post explaining how to adapt comet_messaging.py to
enable bi-directional messaging and to work with true comet techniques
(e.g., long-polling) via Socket.IO (that's actually covered in part 3):
