Putting a variable card in an RFTools Screen should show its value, just like our screens do. Either the screen itself or its controller would have to be hooked up to our network.

Something for https://github.com/CyclopsMC/IntegratedDynamics-Compat

This has been in my mind as well for a while, would definitely be cool to have. But my priority is developing ID/IT itself for now :-)

Feel free to have a go at it yourself if you feel like it.

Note that it should be possible to add the network capability to RFTools screens, which would make them connectable to ID cables.
