Nice idea but what about when the data is all client side that they are dealing with...until they try to hit the server it still won't show a popup.
Any other ideas? The only other thing I can think of combined with yours is have a call made every min or less in a timer that makes a call using your method? Of course this would have to be in something that doesn't leave the screen like in a header or footer I would guess.
