These are just my straw poll of what may be difficult for small enterprises in a change to IPv6.
It isn't "change to", its "add IPv6".
I expect to see IPv4 used for years inside homes and enterprises where there is enough IPv4 addresses to meet the internal needs. It's external communication which needs to switch to IPv6. Internal communication just comes along for the ride.
If people start supplying CPE that are running IPv6 on the outside and IPv4 NAT in the inside, then that would just fine, in the sense that the users (in this case including the self-administrators of these small enterprise networks) won't notice the difference. -- Roland Perry
