In this environment, only one remote console is allowed to connect to the local console at a time.
The users are left to work out an arrangement in which another remote console can access the local console. If this is needed on a regular basis it might be as easy as assigning a time period in which each remote console would access the local console. When the time is up for the first remote, it would release control and disconnect. The next remote would then connect at its assigned time and request control. This assumes that the local console did not have control when the first remote got control.
