If somebody wants to provide a good tunnel broker service they can
automate this without any changes in the clients. Just have multiple tunnel
servers at different places in the topology and have the tunnel broker
meaure or estimate the location of the client before handing it
off to a tunnel server.

Thus if example.net wants to capture IPv6 "customers" that they don't
have as IPv4 customers they could do this relatively easily.

Yes, but see above. A single icon on the desktop might be sufficient.
And it has the advantage of lower operational complexity resulting in
a higher probability that it actually works. And should it not work the icon
allows you turn turn it off.
