That seems like it would have the same problem then.  The upstream  
switch will still have associated the virtual mac address with a  
physical port and the only way it will know the mac address has moved  
to a different physical port is to wait for some sort of traffic from  
the new master.  Though I'm just talking out of my posterior orifice  
at this point... Maybe this works better in practice.
