You are not required to have a Deice VGDS, if you omit its name ( currently, the only model included is "VgdsDeIceWall" ), no display will be shown. There might be different models to choose from in future updates, just like the normal VGDS.
You can specify the position of the Deice VGDS. Without a position, its placement will be based on the deicing area radius, but the .INI supports specific lat/lon/heading for the panel itself.
We'll post some documentation but, it will just be temporary, because a follow up update will feature a complete editor, which will look very similar to a regular parking editor, just the only object editable will be the location of the deicing stand, the stop position and the position of the display.
However, in case deicing is done on a parking stand too, I won't call it a "remote deicing", it's an in-parking deicing that has always been possible before.
