I have, and I plan to use that style of polling as a fallback, specifically
for browsers that don't support websockets (Internet Explorer 9 and below,
Firefox 4, etc). But as Braydon pointed out, polling isn't quite real-time
data exchange.

One option would be to enable websockets on the server if the server is
capable of using them and defaulting to AJAX long polling if it isn't.  If
that's the direction, what's the easiest way to detect *server* support for
the technology?  Browser support is easy to detect using Modernizr ...
