If you do that (which is a nice way to leverage IPv6 to work around
duplicate use of private network segments, by having a NAT64 gateway
for each), then you really do not want to use "arbitrary DNS64" resolvers,
but maybe have the NAT64 address right in the internal DNS, for 
v6-enabled clients...

But yes, just setting up random NAT64 and DNS64 boxes and hoping for
magic to do the right thing might not work out very well.
