What would be the "Debian way" to set up a tunnel between two
routers running Debian to connect two IPv6 islands in an
otherwise IPv4 ocean?
To be a bit more specific:
There are two groups of us in my University who are experimenting
with IPv6. The rest of the University is entirely IPv4.

What is described will work, and will work well.
There is another way to do this, if you are planning to have more
than
two end-points, is you set up the 6to4 addresses on the routers, and
then just add routes to each other. (It just scales better, but if
you
have only two sites, Martin's suggestion is as good or better)
This has the advantage that it also gives you connectivity to the
2002: addresses directly, which are somewhat popular among IPv4-only
home users.
