Ok. IIRC OpenPGM is using raw IP sockets.
There are no ports on that level so we can forget about them for now.
So what you are saying is that when you join a multicast group, network
stack has no concept of individual application, so you'll get all the
packets received on the particular interface, even those that other apps
have subscribed to.
Application A subscribes for 126.96.36.199
Application B subscribes for 188.8.131.52
When packet arrives on 184.108.40.206 it is dispatched to both A and B.
