Need to Push data to Vaadin (7.2) Application from an Application running o

Hi everyone…

I have a Vaadin ( version 7.2 alpha x) Application which consumes data from Rest services running on an external server and displays it in tables (with some extra functionality crud etc.).
I need to be able to push data from the external server application (i.e. not running in the same VM) to my Vaadin app in order to update a table whenever data on external server changes. Anyone know how best to do this? Is there any Vaadin (7.2) specific approach (in addition to the new PUSH functionality) to doing this?

Many thanks in advance for any input/help.
