That sounds like an automatically configured router-advertisment. I 
agree that we don't want that by default but it could be included in the 
 'Shared with other computers' method. We'll explore that later though.

The 6to4 interface could come up and it might even move some traffic but 
there is no way it can work globally since your 6to4 address is based on 
your v4 address and won't be unique. It probably even violates the RFC - 
I don't recall.
