Automatic discovery should be focused within an "autonomous system" 
(enterprise/ISP/etc.). For example, if anycast is used, such address should 
be confined to the autonomous system routing system. How it's done 
(anycast, DNS, etc.) is left to be defined.

I think automatic discovery should be done in order to cover the zero-conf. 
tunneling goals.

In the roaming scenario (or getting service across an IPv4 only ISP), some 
manually configured parameter would be required from the user (e.g. tunnel 
service FQDN of your IPv6 provider). This manual configuration isn't alien 
to users and is done in many client software.
