Element Classic and Ion Classic interaction

A local college theatre has an Ion in the booth and an Element on stage, both on a Net3 network. The installer told them there was no way to use the two boards at the same time and one of them had to be shut down in order for the other to control the rig. They have experimented and not been able to get around the restriction. Is there anything that they could change or add to the system to allow ether client, mirror, backup or remote shutdown/startup to avoid this situation?
