Ask HN: Anyone know of a real-time message board or one in development?

It'd be nice to just leave a message board thread open and watch as the replies are posted. Or similarly watch as comments are posted on HN and elsewhere.

The refresh is slowly being eliminated.

Thoughts?

What technologies would be needed to make this happen? There was a Websockets demo yesterday, which I guess is one way..that hardly seems to be supported by any browsers in use. What else.. is Ajax polling the only other method used now?

Facebook and Twitter and others are doing it, so the technology must be out there.

There were plenty of implementations, at least on the demo level using Websockets & similar.

Here's one example: http://chat.nodejs.org/
