No, that's not possible, in any case polling isn't a problem: it's the 
same application that modifies the table, and it only does the "refresh" 
when necessary.
The problem is that it happens quite frequently (mind me, in a test 
environment, in the field the updates happen once or twice a minute, but 
I'm still not comfortable with the refresh taking too long).
