Good to see your project moving forward Dr_C, looks very well thought through in terms of compatibility with the components used from other systems. I admit that for me its a little tricky to follow because I'm not all that familiar with how all the systems work, but it seems you have a logical approach that will achieve a good robust platform/integration, looks like fun.

Hope its not too early for this but what are the minimum suggested requirements/system components for a system say with 8 cars?

Have fun.
