My fiber ISP provides 6rd connectivity with a /62 prefix address space, and will bump it to /54 when they implement dual-stack on all systems.
There are still legacy routers on the system apparently.
However tomato on my rt-n66u handles the 6rd just fine.
A lot of systems are on ipv6 already, and I think I have around 50/50 ipv6 and ipv4 traffic now. There is no real difference in use for a regular user. Even all the phones, tables and the chromecast use it without me having to do anything except connecting the router.
I still have a regular fixed ip for ipv4, but all my devices are behind nat.
