Comet works. That’s super good to hear.
“Comet is an umbrella term for any technique that allows a web server to “push” events down to a browser.” — Simon Wilson
Imagine web-based chat apps, calendars, and weather widgets that don’t poll the server ever ‘x’ seconds, but rather update only when notified by the server. That’ll save some bandwidth, certainly.
It’s certainly something we’re looking into. We’re already heavily (and happily) invested in AJAX technology, and I think Comet will be a nice addition for some new applications we have in the wings.
