Ok, thanks for the insight. One issue is still that the solution
needs to support the two cases:

   - independent security associations for (S1,G) and (S2,G) if
     G is an SSM group, because (S1,G) and (S2,G) don't necessarily
     have a connection.
   - same security association for (S1,G) and (S2,G) if G is an ASM
     group.

Now how to determine what kind of security association is needed, 
i don't know. Probably it would be a good thing if that could be determined
somewhat application specific, but not necessarily requiring the IPsec
framework to know the distinction between ASM/SSM.

Cheers
