I think you should look at visichat and look at their webcam permissions option and the push to talk options, I feel the chuppo webcam chat on xitti sites needs to be enhanced as certain aspects of it are lacking.
We need a option so we can decide who views our cam.
Also a push to talk option would make the chat more interactive as currently you can only hear a person if you click on their name and it sucks if more than 2 people are on mic.
