Definitely interested to find out what you come up with.  Google fiber does IPv6, but most of the residential IPv6 docs I can find assume your ISP is v4 only, and you're going to use a tunnel broker like HE.

I know very little about v6, and even less about how to configure a router/firewall like pfsense to use v6.  Sometimes feels like trying to learn the interwebs all over again.

Maybe with more residential ISPs like TW making a move, it will start to show the writing on the wall and convince big giant corp like the one I work for that the answer to running out of IPv4 space does not mean more (re)using private, and poaching public, v4 netblocks for internal address space.

I'm told part of the problem is that our clients (hospitals mostly) have flat out said no way to IPv6.
