Async Server Push/Refresh only for current View

Hi,
I’m working with Vaadin 7.1.3. My application have a UI that only handles the flow between authenticated and login area. The navigation within the authenticated is handled entirely by Views.
My question is :
How can I implement a push/refresh async View oriented?
I would like to avoid the implementing of a thread for each view’s component.
I read this for UI class but I do not know if I can adapt it to my needs :
Enabling Server Push

Anyone help me?
Thanks
