Subject: [Roll] multicast DAO

Hi all,
 
regarding usage of multicast DAO: in the following scenario:
  A
 /  \
B  C
 
if the purpose is to to allow B and C to talk to each other directly,
the multicast DAO is equivalent to an unsolicited NA. 
 
In the scenarios like:
 
   A
  /  \
B   C
      |
      D
if the purpose is to have B talk to D through C (instead of A then C),
then the multicast DAO (including destination prefix option) makes
sense. 
Is this scenario needed by some applications?
 
Best,
Julien
