My old site had a very heavy, ajax "shoutbox" style block that allowed users to post quick blurbs in realtime. It quickly became the site "chatbox" as people flooded it with conversation. All the shouts were stored for perusal by users at a later date.
In the new, Drupal, version of this site, we'd like to maintain some of that shoutbox functionality in an ever-present block. It would need to auto-refresh regardless of page-refresh and include a simple timestamp.
I am currently testing this module: http://drupal.org/project/shoutbox
It does fine, but the realtime updating is a little wonky and I've read a security notice on it already: http://secunia.com/advisories/27953/
Are there any other options you folks would suggest?
