We've been running a NAT64/DNS64 set-up for a while now on some parts of our office network. This seems to work well, but it doens't work for everything (e.g. Skype etc).
When it was first being considered there was a non-zero number of us who made an initial effort to explain to the authors that DNS64 was a non-starter because there are always going to be IPv4 sites that hard-code IP addresses, and a non-trivial number of them are going to be critical sites for any given set of users. The authors chose to plunge ahead anyway, leaving us with yet another transition technology "cure" that is worse than the disease.
Dual stack on the inside network is the only (effective) way to address this issue, even if it requires IPv4 NAT at the border.
