NTT (2914) and GBLX (3549) both do native v6...  most everyone else on
the tier1 list does tunnels.  :(

There are some nice tier2 networks who do native v6, tiscali and
come to mind.

GlobalCrossing told me today I can order native IPv6 anywhere on their 
network. Don't know if they count as Tier 1 on your list, though. VZB 
has given me tunnels for a while, hopefully they'll get their pMTU issue

fixed so we can do more interesting things with it.
