I've been trying, it's a bit of a struggle.
Getting my home network on IPv6 was the easiest part. My provider (not Comcast) was no help whatsoever, so I set up a tunnel from HE. Works great. Only time I had to tweak was when my IPv4 endpoint changed addresses, then I login to HE and update my tunnel. The rest of my home network all fell into line, even the mobile devices (iphones mostly) picked up an ipv6 address and use it, but it can be hard to tell since iOS only displays ipv4 info on the wifi settings page.
At work, I don't manage the corporate network, and don't see it moving to ipv6 anytime soon. That's not a barrier for me, except for testing perhaps, though I may be able to configure a tunnel at work as well.
I'm trying to move some of our public sites over, but our data center is handled by a large managed services provider, and they've been dragging their feet for two months on my request to provision ipv6. I don't think they get many requests for it, and I'm not at all sure they know quite how to do it.
It's frustrating to say the least.
