  Without some care to get the routing configuration done right, when that
second implementation's author wants to also advertise the prefix on the 6Bone,
bad things could happen. I'm no BGP wizard, but I think that it might be clever
to grab a private-use ASN and to advertise all instances of this special prefix
out of that ASN. Can someone who is more of a routing geek than I confirm or
refute this?
