This is an interesting question.

In talking to your vendors with your checklist of capabilities a device CAN/SHOULD/MUST have, what if you no longer 
needed to carry 350k/512k routes of IPv4 and only needed 256k of IPv6 ?

Instead of 6pe think of 4pe with ipv6 core.

I've been reminding vendors that IPv6 should get new features *first* vs IPv4.  The end of IPv4 is near, but that 
doesn't mean the end of the Internet is here.  The next chapter gets a new page turned.  Maybe we will determine that 
IPv6 needs to go the way of IPX/Decnet/AppleTalk and some new system (non-IP even) will take over the world.

Either way, it's an interesting time to be an edge operator that worries about CPE stuff.  those that think mostly 
about core this is a big fat *yawn* imho.  Expect application developers to face some interesting challenges.  me?  I'm 
waiting until I see the "NOW WITH IPv6" sticker on things at the store.
