Ajax refresh on multiple tabs

Ajax refresh on multiple tabs

  
I have an application that uses client-side tabs, each of which contains a web block, most web blocks being in different eSpaces. If I change some data on one tab, this may influence data on another tab (e.g. a status of some item may influence the status of another). My question is how I can refresh one or all of the tabs when the user changes data in one of them. Is this possible at all?
notifywidget to trigger the mainpage and then in the update refresh the other widgets, or isn;t that what you want?
