Joomla - Chat and Messenger integration

We would like to integrate Ray widgets (A/V Chat, A/V IM) into Joomla on test site. Chat and IM functions will be accessible only by registered users. User authentication and storage - via Joomla DB. Chat and IM will open in pop-ups by click on the link near the Logged user name. Called user should receive popup to join the conversation.Integration description should allow me to move over to another (not test) domain. Thank You
