Summary
You should now have a clear understanding of how easy it is to adapt our initial video call application to support file sharing. You should be able to update the HTML user interface to add a shared files list. And you should now appreciate even further, how the cleanly abstracted design of the signaling server allows us to easily support new application scenarios.
You should also have all the information you need to start exploring other file sharing options and ideas.
In the final two chapters, we will explore some specific case studies that show how this type of application can be implemented to enable e-learning and team communication.
