Read that white paper again. Look in table 1 at Scenario 4.

also:

" Address Family Translation (AFT), or simply translation, facilitates 
communication between IPv6-only and IPv4-only hosts and networks 
(whether in a transit, an access, or an edge network) by performing IP 
header and address translation between the two address families.
AFT is not a long-term support strategy; it is a medium-term coexistence 
strategy that can be used to facilitate a long-term program of IPv6 
transition by both enterprises and ISPs. "

Any halfway modern router can use dual stack. Any halfway modern OS can 
use dual stack. You just have to design your IPv6 network.
