Hi everyone! 
In my needs, I need to develop an vaadin component to chat. Let’s think about that…
In my application, everyone has a profile, my desire is: if you want, you can click at one user profile, and request a chat. If audio is avaliable, you can call with audio, if webcam is avaliable, you talk with image too, but if neither of those are availables, you can chat with text…
What tools I need to do that? Anybody has suggestions?
Thanks!
