Invision-ish Shoutbox

[k3]

Hi, I'm looking for a shoutbox similar to the one invision offers. Auto refresh, integrated with forum registration, supports BB codes, and doesnt refresh the entire page when shouting. I've looked around a lot and I have found several shoutboxes but nothing quite like this, which allows users to simulate a realtime chat without having to open a whole new window or refresh every 5 seconds.

Whether its part of a portal, plugin, mod, etc it doesnt matter.

If anybody has any ideas, please let me know
