I agree with Simon, that this would be a good idea. The importance of good
IPv4 connectivity for a tunnel should be stressed, i think, especially as
6bone expands.

I would even suggest, that some requirements should be set up for for
tunnels, so that routing would somehow reflect the underlying ipv4 links'
parameters (rtt or hops).

Yes, we have ipv4 ping times around 35ms (11 hops) to SWITCH, while around
180ms (16 hops) to CICNET, with whom we also have a tunnel. In the
meantime, they are all one hop away in ipv6.
