First steps towards v6 support by ATT?

While researching at&t and ipv6 I came across http://www.feise.com/~jfeise/blogs/index.php?blog=8 and also http://www.corp.att.com/gov/solution/network_services/data_nw/ipv6/ Looks like they have established a tunnel in the United States perhaps? I realize that getting native v6 support to DSL users isn't exactly a high priority for US IPSes, but building tunnel servers that are on the same continent as the user base is nice. :) .... of course that tunnel might be broken. Can anyone comment on this?
