But that is where it breaks down which is what I have been saying all along: if the IGate client is integral within a server or if the IGate operator is running their IGate into a local server (local as in private access in their house, for instance) and that server is connected to a limited feed upstream (as it often is), a RX-only IGate can break messaging.
