Charles - I must say thank you for the reply about motivating the
absence of multicast in the autoconf addressing model because of its
ressemblance to broadcast, lack of tools to build trees and dedicated
suitability to non-MANET environments.

I will excuse myself for not replying.  I don't because this group is
not friendly.

Later, when we wonder who owes an answer to whom - it'll be simpler :-)
