Jeroen,
I see it like this:
You can pick anything in fd00::/8 that you want, but if you don't
follow the random selection rules in the RFC then it's *your fault*
when you go to connect a VPN to someone else who picked the same
network.
Also, the DNS is your friend, even more so with IPv6 than with IPv4.
