Please take a look at this Facebook app that I have developed that allows you to chat in group chat rooms with other Facebook users and also create one to one video chats with friends and family members. Add the app and you auto-login into the chat room. It is totally free and uses peer to peer streaming, so no media server is used. It will hopefully become very popular on Facebook. Please check out the app here http://apps.facebook.com/chat-social/ Thank you and hope you enjoy it!
