IPv6-only network--is NAT64+DNS64 really this easy now?

[Mel Pilgrim]

I'm looking to set up a pure-IPv6 environment to test the viability of 
it.  I tried this a few years ago and fell flat on my face due to the 
lack of NAT64 and DNS64 support.

Reading through docs now, it looks like unbound has a DNS64 module, and 
NAT64 is baked into ipfw.  Waving a hand at bug-hunting and lamentations 
over the inertia of embedded systems designers, has it really become 
this easy to turn up an IPv6-only site?
