I am not saying that it cannot be done.  You are missing the
point here.  I am saying that for the sake of saving cost, 
vendors may not do it for a long time, until users demand it.
Users will scream when VCI runs out.  Why would that happen?  
It will be due to application writers using masses of connections.

I wonder what is the number of VCI per port supported in the switches
available today?  And in the near future?  Granted, if every port 
is going to provide 16 million VCI, there would be no need for 
cause 45: "no VPCI/VCI available".  It exists because of the 
reason I suggested.
