WebSockets?

I am looking to use WebSockets in a chat application. I have reason to believe that a competitor has found a way do this within Yii, but I can’t find a single mention of WebSockets anywhere on the site. And it doesn’t help that I’ve never used WebSockets before and have a vague understanding of them at best (though I do know about the compatibility issues, and have that covered already).

So, the question is, can I integrate WebSocket functionality into my Yii application?

Oh, I’m sorry. I spent all that time searching the Yii forums that I forgot to enter the search terms in Google.

… No, not really.

Anyone got any input on specifically implementing WebSockets in Yii?
