Looking for a forum based chat / shoutbox

[utw-Mephisto]

I know there is shoutbox, which is great, but I need any kind of chat / shoutbox system which I can put in a certain sub forum. We have in our forums also a category for spam and we would like to have a chat system in there as well ...

I know we could seperate, but we would like to have it like that ..

Is there something like this out there ?
