Chat not working..want to help test

Hi All!
I know this is in beta and want to help make this a great addition to the wpmu offers.
Seems this plug is having issues..with my setup.. Currently I have chip0 installed and everything is working except chat..multi site 3.21
chatabouttv.com

Chat window shows up but all aspects are blank..
in twenty eleven the text shows but chat still does not work..

My goal is for a public chat window by page/topic seems like this plug can do it?
In a perfect world private rooms would be nice..

I'd like to add additional features like a radio show at some point..is this system extend-able?
1. can we get it to work..?
2. can it be used with out requiring a user/login?

open to help trouble shoot issues..open to testing new features beta projects..
cheers
Darrin
