SV: Microsoft: Give Xbox One users IPv6 connectivity

I don't have numbers for other markets, but in Norway I would say more than 80% have UPnP enabled gateways.  At least the ISP I work for have provided customers with UPnP enabled gateways the last 7+ years.  Most devices I can see in the Norwegian market (online and physical stores) have support for UPnP.

But not to derail the discussion to much.  Even with UPnP enabled, there are apparently very different ways to enterpete how to use UPnP.  Some clients fail misserably if they dont get the port they seek, some release the port as soon as it has been granted (older version of microsoft messenger did this, caused a lot of cpu usage on the gateways).  Some clients do not understand that they have a port, and proceede to the next port and then use up all ports on the gateway.

Do you have numbers on this? My belief has been that most people today who
care about anything more than web surfing would have a decently new
gateway (less than 3-5 years old) and that this would support UPnP.

I don't have any numbers so I would like to know more :)
