I do expect some of these workarounds to be vendor and/or 
platform specific, as more units are deployed and the 
industry simply can't keep up with the various topologies 
and customer elasticities ISP's have to maintain.

We're already seeing evidence of this as we discuss NAT64 
options with vendors, particularly in the area of scale and 
customer experience perceptions.
