This all depends on how your manage your last-mile and terminate users now.  I have a friend with a local WISP here and 
he gives everyone a /24 out of 172.16/12 and dumps them through his load-balancer for his few connections.  His "CGN" 
box seems to handle this fine.

I would say you want to do dual-stack, but shift the users that don't *need* public IPs into 1918 space and deliver v6 
native as feasible.  If you have a server lan, you can do this with SLAAC, but to get the other information to your 
hosts, either via RA's and otherwise, it's just becoming easier to do.

PPPo* you can get IPv6 IPCP up and going, but the device has to support it.

ASR1K and other devices can serve as nat64.. (I think Juniper does the same, but I don't recall their roadmap/product 
set).  I'm sure you can do it with a Linux or *BSD box as well.

I would say there is none as it largely depends on how you terminate that transport, and there are a few ways one can 
do that.

Hope this helps,
