I think it will be used mostly as the middle 4 in NAT444 and in links between networks where there are RFC1918 network assignment collisions. My gut tells me we will see that net block being used for NAT on a lot of VPNs between RFC1918 networks. > I don't think any sane provider will use this as yet another way to > avoid deploying IPv4.
