>From RFC 3971

   To protect Router Discovery, SEND requires that routers be authorized
   to act as routers.  This authorization is provisioned in both routers
   and hosts.  Routers are given certificates from a trust anchor, and
   the hosts are configured with the trust anchor(s) to authorize
   routers.  

That's both significant pre-configuration, and problematic in an ad hoc
network. (The rest of section 6 has a whole lot more complexity.)

I'm just waving my hands and I have no references. But RFC 3971 does 
something similar for SLAAC. Its not the only approach, over the years 
people have looked at different ways in allocating mobile IPv6 home 
addresses as well.

OK. That makes sense.
