Given that routers don't act on Router Advertisements from other routers
I have a hard time to see how the 'master-router-announcer' can make
the whole IPv6 cloud to renumber.  As it stands now, it would require
flicks of many switches (as many as there are routers) to renumber
the entire cloud.  It might be possible (albeit hard) to renumber by commands
from a maser network management station provided we had a set of standard
configuration tools implemented by every router vendor.  But this is not
here as yet.  Any news from the IPv6 MIB WG, BTW?
