A chatbox would be a nice addition to the forums, and I think everyone could benefit from it. Not only could it be the source of quicker updates than typing out a forums post, but it could stimulate some conversation faster than waiting for a certain topic to update.
Most chatboxes come with potential restrictions as well, such as only a certain amount of posts or a certain rank can see the chatbox. They also have spam-filters and things of that nature that help with posting too many messages at once, preventing potential spammers.
Another alternative would be to establish a Web IRC Chatroom, something like what Mibbit does. You could actually place it inside certain topics. It's a nice little widget that allows you to chat with friends and other people within the chatroom, all the while listening to music or watching a video that someone might've linked inside the application.
Just an idea.
