Shout Box with online members list.

Looking for a shout box that would show a list of who is "present" or even "away."

Anyone have a idea on where we could find something like this? From what we see there are a few chat options but none with a list of members.
STill nothing on this? I have looked at the TaigaChat Pro but would like to be able to see who is active. We don't have the shout box on our home page so the block feature that shows the members will not work for us apparently.
We are willing to pay someone to code us something if that is a possibility . Please help... Thanks
