We looked into this somewhat intently ~6 months ago and had not much
luck from vendors. Barely on their radar if at all.

We used our own custom OpenWRT build on a few select, tested consumer
routers to do 464XLAT. In the end we went to dual-stack with CGN on
IPv4. I wrote up some documentation on how we did it on my blog, but in
the end I can't recommend the setup we used.

I would love RouterOS and (various mfgr) CPE support for 464XLAT, then I
would be ready to give it another shot.
