@jch "With Hurricane, I just have the one /64 which is fine for my purposes"
You can apply for a free /48 from Hurricane Electric too (or at least you could at one point).
My router runs OpenWRT, and serves as the 6in4 tunnel endpoint. It delegates a separate /64 from my /48 to each of the subnets on my local network (guest, LAN etc.).
Not as good as having native IPv6, but is pretty good for most things which need IPv6 connectivity.
Zen give their DSL customers a static /48 too.
Ironically since I was in the 2012 Plusnet IPv6 trial (which basically worked fine), my Plusnet IPv4 address has a reverse DNS name of ipv6testX.plus.com
