Maybe what would be useful would be to allot part of the SAID space
for "not assigned by the destination system" (but not implying any
particular "structure"). I think this would make assignment easier.
Whether or not such an allocation is made, an implementation should be
able to solve the collision problem by making <SAID, destination
address> the key, instead of simply <SAID>. Then multicast
address(es) and locally assigned unicast address(es) could have the
same 32-bit SAID without "collision". One might also want some
wildcard address that would match any of the system's unicast
addresses (but not any multicast address); a question for the security
