	Sure...

	For DS, I could send IPv6 native and IPv4 via NAT.  I suspect this 
actually the most common home setup at this point.  It's certainly the 
way mine looks.

	I have noticed that IPv4 "feels" slow on my t-mobile usa connected
devices.  This is only a problem when interacting with legacy players on the
network, eg: financials, opensrs, airlines.  I suspect this is a 64 CGN tax.

	Waiting to see my other devices/sims see IPv6 on them via VZ and AT&T.

	Sure, but your v4 is likely to have issues regardless and face this
penalty/tax.
