Any solution involving polling isn't going to work for what th OP wants 
and I advise everyone never to use polling if there is another option 
available.

For instance how many people know about:

MV.Net has lots of good things in it, but you should never consider 
polling for data when ther is kernel controlled solution available. For 
one thing, polling something every second has the potential to slug a 
machine and the OP wants real time.
