Whiteboard with Voice Chat - Java

***I need a web-based whiteboard and voice chat module for a virtual classroom project. An online meeting room. Both whiteboard and voice chat have to be implemented through Java Applets. They should be able to support multiple sessions i.e. teaching more than one courses should be possible.? In other words, it should be able to support multiple meeting rooms simultaneously.? Each meeting room should be able to support 8-10 attendees.? One person will be the 'host' and a student should be able to join.? Host should have the control to end the meeting, expel any other attendees, erase whiteboard etc.? We would also prefer it if the 'meetings' could be recorded action for action, voice for voice.*** ? ***Each meeting/session when it is scheduled should have a unique identifier.? Only the people that have the identifier should be able to join the meeting. Both students and teachers will login through PHP based page and select the course/session for which they have previously registered and been scheduled.? On clicking a 'start session' button,? they will go to the whiteboard and voice chat module. So, you will have to provide a user management interface.? There should also be sufficient hooks built in, so that an automated scheduling model is supported.? More can be discussed on this.*** *** Whiteboard should provide all the basic drawing functionalities... typically those like in MS Paint.? Ideal features and functionalities are those that are present in webex meeting room whiteboard.***
