I think you also have to consider whether there's something to
tunnel *to* - is there a significantly large class of dual stack
services that will be able to make use of tunnels? And don't forget
the third class of solution: application level proxies. Would
you advise the operator of a large IPv4-only web site to
a) dual-stack the whole site
b) install a dual-stack proxy for IPv6 clients
c) install a layer 3 translator for IPv6 clients?
