Not to my knowledge. traceroute6 shows:

traceroute to ipv6.lkml.org (2001:968:1::2) from

thunder.wiggy.net is my Linux router running 2.4.19-pre5-ac3-freeswan196
currently. The second hop is a normal sit tunnel and all the other
hops are native ipv6 using Cisco and Juniper routers as far as I know.
If you want I can get a detailed list of the routers and the IOS/JunOS
versions they are running.
