Hello Etienne,
I've readden with attention your interesting software development.
I have developped almost the same idea but with another node concept.
Instead of having concurrency, I propose to gather our intelligency to make our both platform cooperative.
Maybe we can find a way to make them usable together.
My software unfortunately is a commercial one. I have no job ...so, no choice.
The concept is to use nodes for any kind of computer language. For example, coding for arduino
or java or python or 3ds Max script or Blue print or anything else. It doesn't matter.
There is a textual help for each node to be able to use fastly and easily.
Moreover, a wysiwyg GUI generator is provided.
It is very powerfull and has a lot of potential in coding a project and I think with your
specialized software, we could make a great tool for arduino.
Look at my website here:

It seems you're french, me also.
