Anyone tinkering with IPv6

Has anyone been preparing your enterprise, small business, etc. for IPv6? I listened to a packet pushers podcast yesterday on the subject and learned that the U.S. is basically just sweeping the issue under the rug, trying to put it off for a few more years. I was curious if anyone here is already using IPv6 or preparing for it. We aren’t where I’m at, but I work for local government and we’re a pretty small operation so we’ll probably not move until told to by our superiors. 🙂
