	If we include the source address for multicast, to accommodate SSM, 
	does that mean I don't have to pay attention to the destination for 
	any multicast protocol. That would be a sort of equal tradeoff, 
	moving from requiring that an SA be defined by source and SPI instead 
	of destination and SPI, for multicast. But I don't want to make life 
	more complex by requiring support for all three.

I don't think we can get away with that. (S,G1) would be a whole different
set of members than (S,G2), and would therefore want to have different keys,
etc.
