IPv6 Confusion

I probably tied CPE to NAT together in my mind....if I peel NAT out from what these CPE are doing, perhaps a PPPoE/A environment is the only place a L3 CPE will be needed with IPv6 anymore.  FTTH, BWA, RFC 1483/RBE, and cable modems can bridge at L2 and each customer host can each have their own IPv6 address.

On the other hand, a majority of the routers purchased are for wireless
connectivity, followed quickly by the necessity for multiple computers
sharing a common subnet. Security and firewalls are not something most
end users attribute to routers, but instead to their host based solutions.

As such, I have no problem with pointing out that they can have 4.3
billion squared devices sitting off a cheap switch; all sharing the same
subnet. Of course, wireless peeps will either have to use wireless
bridges or have supported routers. Really, the AirPort is pretty stable
and functional as a wireless AP. Most say it's worth the extra $$$.
