Regular GPON is already being used to deliver Enterprise services, 
purely because it "passes by the office complex" on its way to the 
residential neighborhood. Even when the Sales team are told not to use 
GPON for Enterprise services, they end up doing so... first as a 
"temporary, we have told the customer all the pitfalls" solution, which 
eventually becomes permanent, and then it grows like wildfire.

You can expect that XG-PON will go the same way.
