This +1.

There are plenty of enterprises, employing actual network engineers (allegedly), who are just about getting to grips with CIDR and VLSM.  They are *thinking* about reconfiguring their hosts to stop having 10.x.x.x/8 as the interface address, and letting proxy-arp on the routers worry about which subnets are which.  They *might* have been convinced that an ATM cloud (or sometimes even MPLS!) has robust traffic separation, and they don't need a full mesh of leased lines any more.

IPv6 is hugely scary as it is, without breaking their "hosts and host info" / "routers and routing info" silo model.  Not all of the networking world runs on Internet time :(
