modify the source code of openmeetings

The project scope: •Develop an application on the LINUX platform to perform at least the following: 1) messaging 2) voice communication 3) "drawingboard" sharing 4) video conferencing 5) impact/noise/vibration/distance sensing •Ensure that the Linux platform can start the application, communicate in between the devices and end the application. I had decided to use the source code of the "Openmeetings" which is an open source program, because its capabilities are most match my project's requirement. I had installed the Openmeetings 2.0 from source code on Ubuntu OS, I also test it between two laptops(both are Ubuntu OS), it works properly. Now, I want to add in some other functions. The Openmeetings includes scope from 1-4 already, so I just want to add in the 5th scope inside the openmeetings. I have the source code for distance sensing. So, you can just use it. More details will be discuss. Thank you!
