diwacs
Diwa is a project collaboration tool.
... capture is taken of the room and a sound recording is saved (if you have the hardware).
The project is still in alpha stage so the documentation is not yet complete, but the code is not overly complex so it should be possible to deploy the system without further assistance if required.
DiWaWa is the webapplication interface for the system and should go hand-in-hand with DiWaCS.
